Answers to Finch's questions
The more I think about this, the more angry I get at the numerous plotholes and stupid character behaviours. Perhaps the film's defenders could answer the following questions?
I don’t know why the film’s defenders would be more capable of answering these questions than yourself, as they possess no special knowledge of the film, but I’ll attempt an answer anyway.
Why did an Alien race which we assume to be engineers revisit Earth many times over?
We don’t know if the Engineers visited Earth a few times or many or for how long they visited it each time. Presumably though, if one or a group of them were interested in creating intelligent life on a planet, they might have enough interest to check back in and see how it’s going.
Why did they point the way to a weapons base on the other side of the galaxy?
Who’s they? My understanding is that the cave paintings were made by people. So the question should be, how did people come to learn about the Engineers? Was it through direct contact or artifacts that the Engineers left? And if/when this contact was made, was the Moon a weapons base and did the Engineers intend to let us know about it. I don’t know that we can answer any of those questions. Also, the star map wasn’t a direct map to the base, simply to a solar system where the Engineers had been.
How does one find the only building on a planet by coincidentally seeing it out of a window on a low flypast?
By luck. Does luck exist?
Why don't scientists study the most important find in history before walking right in to it?
The entire motivation behind the voyage (Shaw, Holloway and Weyland) is to meet the Engineers. I agree, dispassionate scientist in some other movie might be interested in studying them, but it’s clear that the character’s primary interest is to simply meet them.
How does an android know Alien language? Are these languages from cultures that never met each other from the Engineers? If so, is it all Sumerian?
Apparently it’s Holloway’s thesis that the languages spoken by the different civilizations that had knowledge of the Engineers have some similarities that shed light on the Engineers language. I don’t know if they’re all Sumerian.
Why does Weyland not screen the staff it is sending on the most expensive trip ever to filter out the idiots?
Weyland’s daughter was in charge of organizing the trip, so the question should be why doesn’t Vickers screen out the idiots? Next, maybe only idiots are willing to go on long space voyages were practically speaking, if anything goes seriously wrong, there’s no chance of rescue. Next, the mission succeeds to a considerable extent! They find and make contact with the Engineers! They all fail to foresee that another intelligent alien species might be hostile (something which I consider obvious, and so idiotic to have overlooked) but that's Weyland's mistake too.
Why are there axes on a lifeboat ship?
Because they come in handy. There might be many tools on the ship of which the axe was just one. It’s possible that such tools are still very useful in the future.
How can anyone get lost in the pyramid when the bridge can see everyones position at all times?
I agree with you on this. How can the person, in charge of the cave mapping technology, not know how to use it, in order to leave the cave himself? This part was unbelievable.
Why does Holloway get flame throwered but mutant Fifield is let in?
At first, all they know is that Fifield is outside, they only learn after they open the door that he’s infected. They don’t let him in, he rushes in, but given the earlier exposure, they should have been more careful.
How can dreams be watched? Can thoughts be read?
Through some future technology. I don’t know whether it’s conceivably possible or not.
When searching for missing crewmen, why does no one rewind the camera feed to see where they lost transmission?
I don’t think looking at the feed would be the best way to find them. They have motion trackers and I think should be able to triangulate their position based on the feed itself.
Why does Holloway take his helmet off just because there's oxygen in the temple? Has he never heard of airborne diseases?
This was stupid. I could understand his character doing it, but you would think someone else might have realized it and not done it.
Why do Engineers have Elephantine helmets twice the size of their heads?
Do you really need an answer to this question? Is there some universal law that says space helmets must be a certain size?
What happened to kill the Engineers in the temple?
It appears the biological weapons (black goo/worms and lizard creatures) they were developing.
Why does no one bother to find out?
Because they’re not there to investigate or learn about the Engineers. The entire trip was financed simply so that Weyland could meet the Engineers and ask them for immortality. Also, when the group discovers the first engineer it was decapitated by a closing door, they don’t know about the other Engineers corpses. Once the group learns about the leaking canisters and find the other Engineer bodies, Janek quickly surmises what killed them and realizes, along with Vickers, that it’s NOT safe to go into the caves.
What are the snake things? Why don't they infect the host?
The snake things appear to be part of the weapons the Engineers were making. Apparently they, infect the host in two ways, by turning them into a homicidal maniac or by making them a host for a larger creature. I don’t know why it works like this, but I don’t know whether it’s completely implausible that it does work like this.
How did the giant facehugger make a proto xenomorph?
Because they were designed that way. Why were they designed that way? I don’t know. Maybe the engineers intended to wipe out the human race and replace them with the xenomorphs, maybe they weren’t designed that way and it was a totally unforeseen consequence. I'm curious though, how alien squids and the original xenomorphs get so large, so quickly, without any apparent nutritional source.
How does David know the motives of the Engineers?
Does he know them or guess them?
How do you reanimate a severed head?
Do they reanimate it? It appears that they’re just stimulating the muscles in the head to see what they act like.
Why does the captain just accept Shaw's plea to fly into the spaceship when she says 'it's heading to Earth and carrying death'
The Captain makes it clear earlier, that he understands, because of his military background, what the moon base is and how dangerous its contents are. He makes it clear that he’s not willing to let ANYTHING from that cave return to Earth and Shaw agrees with him. Is it really not credible that when faced with the reality that a ship of biological space weapons is headed towards Earth that a solider might not sacrifice his life to stop it?
Anyway, I share some previous posters overall disappointment with the movie, but for some different reasons.
I wish the movie had done something more to imagine and flesh out the future world the characters inhabit, including some depiction of what life on Earth might be like in 2091 (projecting some of our current problems like, climate change, overpopulation, rising food prices, destruction of natural resources, etc.) into the future.
I wish more thought had been given to why and what sort of people would volunteer to go on such long voyages where the risk of mishap and death seems high and what reward or compensation they expect for such work.
I wish some thought had been given to what kind of culture, norms, customs, habits, etc. might develop between people involved in space exploration and how such people might interact with each other. This for me is one of the most unbelievable parts of the movie. All the characters just seem like random people in space. They don't exude any particular professionalism related to space travel or science. One example of this is when an anthropologist is allowed, offhandedly, in a quickly organized venture just before nightfall, to dissuade anyone from bringing weapons with them. Has she ever been to an alien planet or moon before? The planet has an atmosphere and water. Would it have been unreasonable to assume they might encounter indigenous life forms and that some of these might prove harmful to people? Another example is when Shaw discovers an alien life form inside her, removes and traps it, but then, apparently doesn't tell or warn anybody, hey, potentially hostile alien life form on board? Do the characters have any kind of procedures, routines, professionalism about what they do at all? Two characters get trapped underground in a cave and no detail of people can be organized to watch/listen to them over the telecom at night after a potential life form, is potentially detected? One of the strengths, for me, of Alien, is that it takes the time to setup relationships between its characters, which aren't just said, I'm the boss, you're employees, but which are demonstrated through actions. These things give you the sense that you're in a real world and helps to build the characters and our concern for them. Not much of this happens in Prometheus.
I don't wish the movie was ABOUT any of these things, but paying some attention to them and placing them in the background in some way would have added positively to the atmosphere of the movie. Anyway, those are wishes and they're not coming true. For what the movie was, an attempt to answer the question of why are we here, through the context of an Alien "prequel" of sorts, I think the movie worked fairly well and I especially enjoyed the scene between David and Halloway at the pool table, which to me, along with a certain character's sad death near the end, were the best parts of the movie. I'm curious what others think of the pool table scene, since no one has mentioned it specifically.
