College student Evan Treborn (Ashton Kutcher) is afflicted with headaches so painful that he frequently blacks out. While unconscious, Evan is able to travel back in time to difficult moments in his childhood. He can also alter the past for friends, like Kayleigh (Amy Smart), who was molested by her father (Eric Stoltz). But changing the past can drastically alter the present, and Evan finds himself in nightmarish alternate realities, including one where he's locked away in prison.

Critics Consensus

The premise is intriguing, but it's placed in the service of an overwrought and tasteless thriller.

Lobotomised entertainment that's dark, violent, and hilariously dumb.

Flicks (AU, NZ, UK)

This film is so gut-wrenchingly dark and twisted I’d also call it a horror movie, with virtually no respite once its core premise swings into gear.

Wildly uneven and not exactly high-quality entertainment, The Butterfly Effect has, nonetheless, weirdly turned out to be strangely memorable, especially for certain generation of moviegoers.

Rated: 3/5

The Butterfly Effect looks at the power of memory, the repercussions of events from our past that bleed into the present.

I think the viewer's perception of this movie changes with age and that it should be definitely viewed when you're over 35 and you've gained some life experience that will allow you to be emotionally engaged in this story. I'm pretty sure many of the critics didn't quite get it right at first watch. Been there, done that myself when it came out. Now, 20+ years later, I'm pretty baffled by how good this movie actually is! And be aware, the Director's Cut ending is totally different from the theatrical and you should definitely watch both and choose the one that fits your emotional needs :)

A linha principal do tempo foi modificada várias vezes, mas mesmo assim o protagonista conseguiu viver em uma outra realidade, culpando kayleigth de uma forma inesperada. Mas não era culpa dela que os eventos trágicos aconteceram, mas do pai e do irmão dela. Daí fica aquela pergunta: O que aconteceu com ela e sua família disfuncional? Você nunca vai saber.
