Emma Stone and Ryan Gosling in Gangster Squad.

The release date of Gangster Squad was delayed after the Aurora, Colo., theater shootings, due to a scene depicting violence in a movie theater. That scene, which was featured in the trailer, has been removed.

Well, they shouldโ€™ve scrapped the whole picture. This movie is a mess.

Gangster Squad depicts a fictional account of the Los Angeles Police Departmentโ€™s โ€œunder the tableโ€ efforts to remove gangster Mickey Cohen (played here by a truly awful Sean Penn) from power. While next to nothing in this movie actually happened, I can forgive a little artistic license when it comes to a gangster pic.

What I canโ€™t forgive is cartoon caricatures, terrible performances, a misguided directorial tone and a crappy screenplay.

The film is set in 1949 Los Angeles, where Cohen has a firm grip on organized crime and the cops. Well-meaning LAPD Chief Parker (a typically grizzly Nick Nolte) tells brave Sgt. John Oโ€™Mara (Josh Brolin) to leave his badge at home; gather a squad of badasses; and disrupt Cohenโ€™s operations.

The squad includes soft-voiced Sgt. Jerry Wooters (Ryan Gosling), an officer who plays with his lighter a lot. Thereโ€™s also the brainiac (Giovanni Ribisi) who will spend much of the movie wearing headphones and tinkering with things.

Thereโ€™s the knife-wielding officer, Coleman Harris (Anthony Mackie), who will throw a knife at someoneโ€™s hand in a crowded nightclub, even though heโ€™s a cop and probably shouldnโ€™t be doing things like that. And, finally, thereโ€™s the comic-book hero (Robert Patrick) and his sidekick (Michael Peรฑa), two wisecracks who are great with their guns.

Director Ruben Fleischer is shooting for an authentic late-โ€™40s gangster-film feel, he but achieves something more akin to parody. The film feels like a bunch of usually decent actors are playing dress-up with their toy guns; they all seem lost.

Emma Stone wastes her time as perhaps the filmโ€™s most-bizarre character. She is Cohenโ€™s etiquette coach (rather than making her a straight-up hooker), somebody who is sleeping with a monster and then two-timing him with Goslingโ€™s Wooters.

Good luck trying to make that character sympathetic. They dress Stone in heavy makeup and flashy dresses, and feed her terrible dialogue. Sheโ€™s completely wrong for the role, although I would have a hard time picking somebody right for it.

Penn has chewed scenery before (I Am Sam, Casualties of War). This time out, he doesnโ€™t just chew the scenery; heโ€™s a freaking wood-chipper. I appreciate Penn as an actor, but sometimesโ€”just sometimesโ€”he can be terrible. This is one of those times.

Regrettably, the usually reliable Gosling is just as bad, and perhaps worse. He decides to utilize a voice that makes him sound like a 12 year-old kid doing a lame James Cagney impersonation. Itโ€™s bad to the point of distraction, as is his action of constantly flipping his lighter. We get it, Ryan Gosling โ€ฆ you learned how to flip your lighter, โ€™40s style. Now knock it off.

Gangster Squad lacks originality, a sense of purpose, style, class, Michael Keaton (although it feels like his Johnny Dangerously character could pop out any moment) and a basic overall reason for being. The problem wasnโ€™t the violent movie-theater scene they had to excise. The whole damn thing stinks. 

Gangster Squad is playing at theaters across the valley.
