Jeremy of The Daily Rotation wrote, "Comedy director Ruben Fleischer switches genres for the 40s mobster film Gangster Squad. What works best is Fleischer’s ability to work great with a larger cast, never losing focus on the story or its key players. What doesn’t work is the film’s inability to become something remotely different when compared to other films of the genre. Gangster Squad isn’t a flop, but it’s far from a creative masterpiece. Fleischer’s got a great eye for comedy and a fairly competent one for action, but the film never slides past being just acceptable."
