Movie Review - "The Butterfly Effect"

... drama about a man who can change the future by going back to the past.

Using a personal journal to remember a past event in his life, he travels back in time, changes the event's outcome, and thereby changes his life.

Unfortunately, one change in the past could result in a death of a friend or family, lost love, or opportunity.

Good movie. Check it out sometime. If you are an optimist, view the theatrical version. If you are a pessimist, view the director's cut.
