Slant Magazine

High school students (the jocks, the brains, the princesses, the criminals, the basket cases), long the favored prey of serial killers, somehow manage to fight back from the brink yet again in Detention, a bright, witty new genre mash-up.

New York Magazine (Vulture)

You admire the movie for refusing to ever, ever slow down, but you also wonder what might have happened had Kahn dared to settle, even just a bit. Instead, what we get is a mad kaleidoscope of genre, with occasional glimpses into the mysteries of the exploding teenage heart.

The Hollywood Reporter

Moves at an absurd pace and dares anyone above 25 to keep up, yet the stream of genre-hopping jokes and sight gags makes the movie an entertaining ride.

The movie itself is never truly clear. If it's also never intentionally bad, its unintentional badness keeps blasting into shockingly clever places.

It's as if the TV character Dawson directed "Heathers," or another one, Parker Lewis, remade "Scream." Who'd have guessed that would be a can't-lose idea?

Detention has a frenetic visual style that's fun and appealing in a lot of ways, but there are way too many elements fighting for attention.

San Francisco Chronicle

By Peter Hartlaub
The high school comedy/drama morphs into a slasher movie, then morphs into a time-traveling/body-switching/world's-about-to-end science fiction story. Everyone on the set must have been chugging Mountain Dew between takes. I suspect that the editor was hooked up to an IV of the beverage.

The New York Times

Horror fans will probably grow impatient with the unevenly executed "Scream"-style self-awareness, and Mr. Kahn ultimately loses control of his referential plate-spinning, in what might be another illustration that catering to short attention spans leads only to mutually assured distraction.

Detention does have imaginative editing and a stylish, candy-colored look - that is, so long as no one's vomiting, an activity that takes up an ungodly portion of the running time.

Time Out New York

By Joshua Rothkopf
From the auteur of "Torque" (2004) comes this instant headache: a panicky snark-schlock horror-comedy that reduces everything to a hyperactive squall of white noise.
