I saw the Butterfly Effect yesterday. Here are my thoughts.
The whole concept is incredible and mind-boggling, and I love it. It was an extremely well-acted film, especially Ashton for being in a dramatic role when we're used to seeing him do comedic stuff; he did an incredible job. At some points I felt like it was just gonna go back and forth forever, and when it finally ended, I was like, wait...that's not how it's supposed to happen! You get really into it. There are some scenes that are really disturbing and not for the faint-of-heart, but it was all really, really interesting with how it all played into the concept of the butterfly effect. It really makes you think, "what if....?"
