Hey guys the only reason I am reviewing this movie( although its pretty old) is because I feel this movie is one of the best Ive ever seen . the script is so good and different, with one theory that even the wing of a butterfly could change the entire universe . haha relax guys its just a theory . the movie is way above . aston kutcher used to get black outs in his childhood . and when he grew up he would start his life in a completly different scenario based on the incidents back in childhood . I am not gonna spoil the movie and I didnt . its an highly recommended movie for everyone . infact aston kutcher got famous after this movie . thanks guys!
