Joseph Gordon-Levitt wrote, directed and stars as a character who looks and acts like he stepped out of “Jersey Shore:” brusque, muscular, shallow, sexy and a total stud. When he meets the girl of his dreams (Scarlett Johannson who embodies the tough, slutty borough girl), his obsession with pornography becomes an issue. This is a fast-paced, quick-witted character study about a man who’s more of a mess than he seems. Gordon-Levitt has fully immersed himself in the character and it’s a winner. His scenes of dinner with his dad (Tony Danza) are great fun. It’s a bit raunchy, if you have a problem with that and not all that deep, but it’s entertaining as hell and bodes well for his hyphenate talent.
