Although the plot holds some potential as a pulpy guilty pleasure, director Joe Carnahan struggles to find his groove. The setup sections are poorly done, providing insufficient information and depending on later flashbacks to explain how the firestorm began. Carnahan then loads the key characters with tedious, eye-rolling platitudes at a time when the picture should be moving faster, slowing the film to a crawl.
Aside from the pacing flaws, “Copshop” can’t decide whether it wants to be a thoughtful action film or pure comic-book mayhem. It tries to be both but only succeeds in being neither. When the film tries to delve deeper, it just serves to reinforce the reality that none of these characters have any depth. As the body count rises, we begin to lose interest in any of these characters, with the possible exception of Valerie, who is caught in the center of Teddy and Bob’s dispute. IMDB
