Ah... that's what I heard about the director's cut... This sounds weird, but I think I'd actually enjoy it more if it DIDN'T make lots of sense, so I could draw my own conclusions... That's one thing I love about the original film, its ambiguity. I dunno, I'm tempted to get the director's cut just to see if any of my theories were right.
Okay, quick synopsis of the basic idea, no spoilers of the ending, just the sort of thing you'd get on the blurb...
Donnie Darko is a brilliantly talented, but confused and angst-ridden teen, who has to go and see a psychiatrist because of his many problems, among them sleepwalking around the countryside at night. One night, he is woken up and ordered outside by a giant, freaky bunny rabbit called Frank, who tells him that the world is going to end in twenty-eight days. While he is out of the house, a jet engine falls from the sky and destroys his room. No one knows where it came from.
And then it starts to get WEIRD.
Basically, don't watch it if you don't like being confused, and if you don't like slightly weird things. This IS a Johan sort of film.
Brilliant.
