Perhaps it's time for director Kevin Smith to focus on something he's shown some real talent at — namely publicity stunts — rather than directing movies.
"...works as a love letter to film fandom, and, amid the ample violence and genitalia jokes, its strength is its sincerity."
— Karina Longworth, Village Voice
"...there's not a whole lot to Cop Out besides watching Kevin Smith pretend, with a crudeness that is simply boring, that he's an action director making a comic thriller about cops versus a Mexican drug gang (yawn)."
— Owen Gleiberman, Entertainment Weekly
"A lot of the dialogue is intended as funny, but man, is it lame."
— Roger Ebert, Chicago Sun-Times
"Cop Out marks indie hero [Kevin] Smith's first attempt to direct a script he did not write and given the absence of his garrulous dialogue and sweetly obscene sensibilities, the shortcomings of his craft are made all the more apparent."
— Andrew Barker, Variety
"...doesn't cop out on talking the talk, but it falls down on the job whenever it comes to walking the walk."
— Michael Rechtshaffen, Hollywood Reporter
