Rating: Null/10 (1 February 2005)

Hey there.. I'm danish so bare over with my spelling..
I have seen the butterfly effect twice.. both times with different kind of ending..
1) where Evan in the end is laying under the table and riding his last letter" if anyone reads this i'm dead ......" then he goes back to his mothers belly and kills himself...
2) again under the table riding the last letter, he goes back to where him and Kayleigh meet each other for the first time.. Here he decides to say something to the girl that he at this time don't know yet, and she decides to move to her mother and not her father, that was Evans plan, so they never get to know each other.. And many years later they pass each other in a street in new york, they turn around for a sec, but move on..
I don't understand why there are two different kinds of endings to a movie, and it irritates me.. WHY?
Next to that, my comment to the movie is: * GOOD movie, gives me something to think of, and helps me to make the right choices in life. * The blackouts cause's, Evans in and out tours... * Yes the journal is existing cause he is traveling all over in the past and in the future, so the journals is coming with him all over. thats it.. Hope you'll help me understand why there's to different kinds of endings.. HI from Denmark
