The Butterfly Effect was suprisingly good. I wasn't quite sure what to expect, and it was actually something good. It deals with an interesting approach to time travel, though that's not the aim of the film.
I found it quite unpredictable which is a good thing, though some of the sequences are unpredictable due to the violence being depicted, it was well shown and not dwelled on. Ashton Kutcher's role in this film must have been his most serious role to date, his character (Evan) was very well acted and never resorted to comedy like most of his other roles. If priced right, this will be making it into my dvd collection.
