Gangster squad tells the story of undercover cops who under the leadership of John O'Mara (Josh Brolin) hunt down mafia kingpin Mickey Cohen's operations and finally nailing him to the jail. Subplot tells the relationship between Jerry (Ryan Gosling) and Grace (Emma Stone) who's a lady love of Mickey cohen. Sean penn who plays a role of cold and ruthless mobster was terrific. Josh Brolin gives a memorable performance as Seargent O'Mara. GIovanni Ribisi's lives up to his original role. Overall a great entertainer for a weekend.
