“Rob the Mob” is now playing at Sundance Cinemas. R, 1;44, three stars out of four.
From the outside, “Rob the Mob” looks like it’ll be a gritty slice of gangster life. But when you see it’s directed by Raymond De Fellitta, who made some ingratiating Italian-American comedy-dramas in “City Island” and “Two Family House,” you suspect that beneath the gunplay and fuhgettaboutits beats a sentimental heart. The f-bombs are hurled, but lovingly.
