Director John Hamburg’s I Love You, Man, which he also co-wrote with Larry Levin, purports to be a movie about male friendships in middle age, but really it is an apologia for our culture’s extension of adolescence into middle age. The friendship under consideration here is between 30-something Los Angeles real estate agent Peter Klaven (Paul Rudd) and Sydney Fife (Jason Segel), a guy he meets at one of his open houses who cheerfully confesses that he has come only for the food. Recently engaged, Peter has been shamed by overhearing his fiancée, Zooey (Rashida Jones), tell a group of her girlfriends that “I think his mom’s his best friend.” Even his younger gay brother, Robbie (Andy Samberg), a fitness instructor, seems to know more about male-bonding than he does, while his dad (J.K. Simmons) woundingly says that Robbie is his own best friend. Naturally, Peter turns to Robbie for advice. Hollywood’s Magic Gay Guy is today what its Magic Negro was a decade or so ago.
