It’s a bit disappointing that Ruben Fleischer‘s Gangster Squad can live in such a rich setting and still feel so light. As seen through a grand tradition of films dating back over 70 years, post-war Los Angeles was boozy, hedonistic, dangerous, and dark. Gangster Squad waters down this colorful world, and simply coasts on being an amusing, frivolous action film. There’s nothing wrong with that, and with a strong cast at his disposal, Fleischer finds a nice blend between the style he brought to Zombieland and the spirit of the time period. Unfortunately, a thin plot and even thinner characters make Gangster Squad as intense as a drive-by shooting and just as fleeting.
