I may as well derail this thread for a post or two by mentioning something I consider noteworthy. Yesterday I bought the director's cut of Donnie Darko (it comes in a cool looking white sleeve and has an extra special features disk) - and it was a totally different movie, basically. And Frankly (pun intended), I had a hard time believing that it was a director's cut because it sucked compared to the one released in theaters initially. If anyone's seen this version you'll know what I mean. It basically explains everything and leaves nothing up for speculation. They show what is inside the philosophy of time travel book in between key scenes, which basically does nothing except replace speculation as to the meaning of the film with bewilderment and confusion if it's the first time someone had seen the movie. And it just looks like a monkey with a pair of scissors edited it. Plenty of scenes that simply weren't in the initial release, and even a voice over at the end that reads the note Donnie put in old lady death's mailbox before "saving the world." Also, there are scenes where he actually blatantly says things like "I am the savior."
I guess I was under the impression that the director's cut would be an improvement, but it took away the mystique of the original release and replaced it with crap. I recommend everyone pick up a copy right away just to see how they fucked it up.
When the film was released, they had the philosophy of time travel book available on the website. It was never the directors intention of making the movie so confusing. That said I think the original theatrical release is a lot better, the director tries to cram too much in and all the cuts and crypticism really do make it a better movie.
