Mysterious enough that many viewers will insist on seeing it twice.
Deborah Young, Hollywood Reporter
As hauntingly strange as it is inconclusive and frustrating, Enemy, directed by Denis Villeneuve (Incendies), is one of the more head-scratching additions to the doppelganger genre. Yet it will certainly have its fans.
David Ehrlich, Film.com
Might have the scariest ending of any film ever made.
David Nusair, Reel Film Reviews
...it's hard to deny that the film, which boasts an impressively memorable final few minutes, lingers in one's consciousness long after the end credits have rolled.
Jason Gorber, Twitch
A highly stylized yet intriguing look at a man coming to terms with his duplicate...Enemy firmly establishes Villeneuve as one of today's most truly unique filmmakers.
Nathaniel Rogers, Film Experience
I kinda dug it but I have no idea if it's any good or what happened or where I am anymore and what aiiiiiiiieeeeeeee that last sound/shot. WTF
Anthony Kaufman, Screen International
A slow-burning metaphysical thriller that stays one step ahead of its audience.
Rodrigo Perez, The Playlist
Thick with weighty themes, disquieting portent and anxious tension, Villeneuve...crafts a gripping slow burn portrait of the male id/ego, our self-destructive tendencies and how they control us.
