The Waters audio-commentary is always interesting to hear and terrific fun as well and this one didn't disapoint either. He even starts it off by saying: "Yes, I'm John Waters and I made this film."
The best thing about the special features is the 47 minutes featurette on the making of the film: you get to see all the gang that made it and see if the years have been kind to them or not (poor old Hatchet Face is now very thin, almost anorexic-like and is a lawyer, no less!).
The only thing I have bugging me with this new Director's Cut is that overall you don't see much difference between what was and now is and the most curious of all is that the best scenes that were left out of the movie in the first place he never got around to include them on this new version so they are in the Deleted Scenes option of the bonus features. A dirty shame, Mr. Waters!
