By now it's been widely noted that "I Love You, Man" is not a Judd Apatow comedy — although it's like one. The stars, Paul Rudd and Jason Segel, have previously featured in two of Apatow's biggest hits, "Knocked Up" and "Forgetting Sarah Marshall." And while the story — yet another expedition into the dark, cluttered heart of Guyville — isn't as besiegingly gross as some of the master's best work, it's nevertheless rousingly funny at times, and overarchingly sweet, in the Apatow manner. It's also naggingly implausible, though, which may be a minor annoyance even for the movie's designated demographic.
Rudd plays Peter Klaven, a hyper-mild-mannered Los Angeles real-estate agent. If nothing else, Peter is the perfect boyfriend — the kind of guy who, upon coming home to find his fiancйe, Zooey (Rashida Jones), in full twitter with her gossipy girlfriends, will slip into the kitchen to whip up a tray of root-beer floats for them. Very cute — and (in the movie's view) kinda gay. For reasons that are not at all clear, Peter has no male friends, no buddies. This has apparently never been a problem until now: With a wedding coming up, he realizes he's going to need a best man.
