All-time best movie; cannot be outdone.

Rating: 10/10 (24 February 2004)

If only A. Kutcher had made thrillers all this time, instead of wasting his time on low-brow teen comedies (DUDE, WHERE'S MY CAR?)... he could've, should've, and WOULD'VE been one of, if not 'the' biggest and most highly paid actors in Hollywood.
Any minute detail of the film I reveal would probably ruin it because it's probably "changed" during the course of the film, but I can sum it up for you...
Ashton ('s character) keeps journals of everything that happens every day, as instructed by his father. Because of a rare brain disease, passed on by his father, he can read any part of that journal and zap back to that point, change one or two details, then zap back to the present. The only problem with this uber-cool ability is that it can effect the present direly.
It's confusing at first, but it eases you into understanding very quickly.
