A political black comedy without the bite of the classic military satires it tries to emulate.
Jay Weissberg - Variety
A movie that doesn't know whether it is slapstick comedy, satire, mystery or a schlock horror flick. Whatever it is, it is highly derivative, and of little consequence.
Susan Walker - Toronto Star
A jack of all formulas and master of none.
Kate Taylor - Globe and Mail
Succeeds in creating a languid, almost hypnotic portrait of go-nowhere, do-nothing peacetime military life.

"Guy X" wins the prize for most boring, pointless and disappointing war movie of the year.
Angela Baldassarre - Sympatico.ca
Guy X could be the weirdest failure of the year. It's also not for anyone prone to soft-tissue neck injury, so abruptly does it switch gears from one movie to another.
Jim Slotek - Jam! Movies
While there's an enjoyable subversive atmosphere, the story simply isn't sharp enough to mean much of anything
Rich Cline - Shadows on the Wall
A film which lingers and haunts, but never compels.
Nev Pierce - BBC
Brilliantly told and will remain with you as you leave the theatre.

David Edwards - Daily Mirror [UK]
Jason Biggs (doomed to have some variation of the words 'pie-botherer' in every article ever written about him thanks to the American Pie movies) makes a successful leap from comedy to drama here.
