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.

| Original Score: 3/5 | Jan 12, 2022

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

| Original Score: 3.5/5 | May 5, 2019

...an above-average time travel picture that ultimately utilizes (and exploits) its out-there premise quite nicely.

| Original Score: 3.5/4 | Aug 16, 2016

The movie tries to be too visceral, and it just comes out as being repugnant

| Original Score: 2.5/5 | Jan 17, 2016

Ouch. Ouch. Ouch. So very bad.

| Original Score: 1/5 | Dec 28, 2010

It's a pretty dumb and utterly pretentious jumbled drama that is never sure what it's trying to say, or what in fact it means.

Tries hard to be affecting and mind-blowing, and sometimes it comes close.

Assez bien dans l'ensemble, mais la fascinante prmise n'est jamais vraiment exploit sa hauteur.

Despite a fairly upbeat ending, the ugly images dominate the film with the time/reality plot a bloody nose afterthought.

Full Review | Original Score: C- | Oct 14, 2004

Cool theories...don't necessarily guarantee good stories...[even if Ashton Kutcher] is repeatedly punk'd by the space-time continuum.

| Sep 24, 2004

Walks a super-thin line between horrific believability and hilarious unbelievability.

| Original Score: 6/10 | Aug 10, 2004

One of the most thoughtful films of 2004.
