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.

The Butterfly Effect is a uniquely strange film that works to its advantage, particularly with Ashton Kutcher's dramatic performance, which will intrigue some audiences and leave others feeling it's a bit corny. Nevertheless, I found the film intriguing. Grading: B

Critics get off on being controversial but honestly just read half their reviews and you can see where they like on the IQ charts 😂 This movie is a staple in its years and it is definitely a classic I have only heard good things about it from countless people. It surrounds the main character having memory deficits that present from blackouts. The character grows up around damaging conditions to anyone in their early to adolescent development years and the audience sees the impact and direction it leads characters down in their lifes. To help with his memory the main uses a tracking method in attempt to fix the issue and finds a power in remembering that leads the movie through the importance of every decision and how it may impact our life trajectory. It is one of a kind in this area of psychological thrillers but leans towards the psychological portion. It is very interesting to think about and makes you think how we as humans are imperfect and sometimes dwell on our past mistakes and forget to capitilize in the present. Do things really happen for a reason in our lives and can you guarantee correcting a mistake will lead you to a better future?

The critics hardly ever have taste. They'll sit there and tell you that movies like "There Will Be Blood" or "Crimes of the Future" or any boring narrative less movie by Wes Anderson is great cinema. This is a classic and enjoyable. Ashton did great too
