John Monaghan, Detroit Free Press: Chalk this up as another misfire in Kutcher's big-screen career. Read more
Connie Ogle, Miami Herald: Better than you might expect despite its awkward, slow beginning, drawing you in gradually and paying off in surprisingly effective and bittersweet ways. Read more
Mark Caro, Chicago Tribune: Aside from this movie's switcheroos, it's hard to pinpoint the entertainment value here. Read more
Moira MacDonald, Seattle Times: Ultimately just feels like a mess, screeching back and forth in time, dragging its actors from one miserable scene to another. Read more
Bob Longino, Atlanta Journal-Constitution: It's a movie as ridiculously weird as it is ludicrously stitched together. Read more
Ty Burr, Boston Globe: A film of singularly boneheaded conceits, Butterfly is populated by, and appears to have been made by, stoned college dudes more hung up on oh-wow twists than the need to make sense. Read more
Manohla Dargis, Los Angeles Times: Maladroit exploitation flick. Read more
Michael Booth, Denver Post: A dopey script personified by Kutcher's dopey, immutable hair style morphs Rashomon into Dude, Where's My Karma? Read more
Owen Gleiberman, Entertainment Weekly: Kutcher is the wrong actor to anchor a psychological freak-out. Read more
Philip Wuntch, Dallas Morning News: At times its awfulness becomes so awesome, it almost must be seen to be believed. Read more
Ella Taylor, L.A. Weekly: Overwritten, overplotted, overacted, risibly incomprehensible. Read more
Lisa Rose, Newark Star-Ledger: The twists and tendrils don't withstand close or even not-so-close scrutiny. Read more
Jack Mathews, New York Daily News: If you approach this movie in the right frame of mind -- that is, with total contempt -- you can still enjoy it as a comedy. Read more
Rex Reed, New York Observer: Not one second of this bilge makes a lick of sense. Read more
Dave Kehr, New York Times: Even by the lax standards of January film releases -- this month is the traditional dumping time for studio films that didn't quite work out -- The Butterfly Effect is staggeringly bad. Read more
Roger Moore, Orlando Sentinel: Kutcher scores laughs, both intentional and otherwise, and only seems at home in those Dude, Where's My Car? moments. And dude brings everybody else down with him. Read more
James Berardinelli, ReelViews: This is a compelling and intriguing movie that toys with the powers of choice and chance in a way that is not overused. Read more
Roger Ebert, Chicago Sun-Times: There's so much flashing forward and backward, so many spins of fate, so many chapters in the journals, that after awhile I felt that I, as well as time, was being jerked around. Read more
Mick LaSalle, San Francisco Chronicle: It's trash, and yet there will always be a place for this kind of trash at the movies. Read more
Michael Agger, Slate: It's as if [Kutcher] decided that he would prove himself as a dramatic actor by trying out every cliched serious role in the history of cinema. Read more
Jeff Strickler, Minneapolis Star Tribune: A morbid tale that careens from child porn to animal abuse to babies being blown up by dynamite. Read more
Rick Groen, Globe and Mail: What if on my way to the screening, something had intervened -- a runaway bus, a lightning bolt -- to prevent me from ever seeing this movie. How would my life have changed? Would I have become a happier, a kinder, a less bitter and disappointed man? Read more
Peter Howell, Toronto Star: A grim and gruesome sci-fi thriller that labours to demonstrate [Kutcher's] range as a dramatic actor. Read more
Mike Clark, USA Today: [Kutcher] is far less interesting than Effect's concept, which in turn is far more interesting than witnessing its botch of an execution. Read more
Dennis Lim, Village Voice: Dreary and overfamiliar -- a strained bid for Donnie Darko cult cred on the part of its star. Read more
