In 7 words or less: Man transports himself into his younger self
What's it all About? Ashton Kutcher finds that he can travel into the past (never explained how) and occupy his younger self during times of stress but at the cost of changing history. Uh oh.
Best bits? Ashton Kutcher in, 'Wait a minute, this film doesn't massively suck' shocker, is a fairly big achievement.
Did it make you think thoughts? Some of the flashback/past scenes are fairly tense and add some meat to the bones of a fairly standard time travel affair.
Would you watch it again? Probably not. Better time travel films to watch are, Back to the Future (all three), Terminator, Groundhog Day, It's a Wonderful Life and Planet of the Apes.
Rating (out of 100%): It's not as poor as you might think. I give The Butterfly Effect a watchable 55%
