To watch Possession again is to realize that it remains one of the most grueling, powerful, and overwhelmingly intense cinematic experiences that you are likely to have in your lifetime.

The Guardian

The polar opposite of a date movie, Possession is incredibly well directed and acted (great soundtrack and camerawork too). Neill and Adjani are both at the height of their powers here, free of ego and fearless. She, in particular, has one relentless freakout scene that you'll never forget. We're still no closer to finding a category for it, but it doesn't need one. [27 July 2013, p.23]

Chicago Reader

That's as good a way as any of describing Zulawski's confounding masterpiece. Possession conveys the fear that some terrible rift—madness, war, apocalypse—might sever us from our own identity. Zulawski communicates this by perverting nearly every convention of narrative cinema—even the exterior shots, which we count on to provide a sense of geography.

Slant Magazine

Many directors have taken full advantage of Adjani’s exotic, ethereal French beauty; only Zulawski saw beyond the exquisite surface to something unsettling. Most disconcerting is the way Adjani can register almost demonic ill-intent while never losing some trace of the alluring.

Time Out by Tom Huddleston

There are plenty of movies which seem to have been made by madmen. Possession may be the only film in existence which is itself mad: unpredictable, horrific, its moments of terrifying lucidity only serving to highlight the staggering derangement at its core. Extreme but essential viewing.

Boston Globe by Wesley Morris

The genius of Zulawski is that he's dispensed with all the buildup and explanation and logic. How many horror-movie explanations make any sense? He just made an entire movie out of the scary parts, the way a different genius concocted only the muffin top and some pop music producers give you 10 minutes of beats and chorus. Possession climaxes for two whole hours. It's as if, with "The Shining," Stanley Kubrick found 25 variations on "here's Johnny" and "red rum." [17 Nov 2012, p.G5]

Pic’s mass of symbols and unbridled, brilliant directing meld this disparate tale into a film that could get cult following on its many levels of symbolism and exploitation.

USA Today by Mike Clark

The result may prove to be too much for even cult horror nuts. This complete 121-minute "director's cut" is tough to follow, so you can see why home viewers were mystified by the early '80s Vestron tape that cut nearly 40 minutes out of the movie and scrambled the order of scenes.

The New York Times by Vincent Canby

It's a movie that contains a certain amount of unseemly gore and makes no sense whatsoever.

An enormous number of symbols--sexual, religious, and political--collide randomly in this pretentious, incoherent horror story.
