Well, I finally saw it (thankyou SBS).
If anything, I wish I could get rid of my habit of accidently finding out how stories end before experiencing them. Damn, damn, damn, damn. The fact that I already knew what would happen may have something to do with this, but I had mixed feelings about it. While it did one of the things that film, in my mind, is supposed to do: Take the audience on an emotional journey. I found it moving, even though I didn't really come to like Donnie that much.
The problem is, that I'm not sure at all whether Donnie Darko was meticulously plotted and engineered to leave it so open to interpretation or whether it just wasn't well thought out. Who the hell was Frank? Who the hell were those dudes at Grandma Death's place? What the hell did the english teacher have to do with anything? Maybe I just need to see it another twelve times.
One thing I know is that if I ever make a film I am so stealing the director's fluid camera movements and occasional odd angles. That scene where they get off the school bus: Genius!
