Replying to Butterfly Effect

Well since the last Astin Kutcher movie I saw was 'Just Married' there was no way this could be worse. Actually I enjoyed this movie. Some of my friends commented on how they thought that they kind of took the audience as not that intelligent because they made the phemenon very easy to understand. But I thought the suspense lied in the all the scenarios that could happen next. Anyway... I thought this movie good, but I couldn't relax during any part of the movie... very anxious.
