No one plays an affable, adorable, yet slightly clueless, guy better than Paul Rudd. In this winning bromance, he's Peter Klaven, fiance to Zooey (Rashida Jones -- Jim's ex-girlfriend from the Scranton branch of Dunder Mifflin in The Office and daughter of Quincy Jones and The Mod Squad's Peggy Lipton). Zooey has dozens of close girlfriends and quickly puts together her line-up of bridesmaids for the big day. Yet, Peter has no fellas to serve as his groomsmen. His gay brother (for a pleasant change, not the stereotypical queeny kind -- funny though that can be), played by Andy Samberg, is better at male friendships than Peter.
Even their father (the dad from Juno) considers the gay son to be his best friend. Peter can't even get his own dad to respect him. Yet, he's so darn good-natured about it. He takes his family's ribbing in stride.
Peter sets off on a quest to find what a girl might call a BFF. After a few funny misfires, he happens upon Sydney (Jason Segel), a beer-swillin', motorcycle-ridin', skirt-chasin', trash-talkin' man's man. Would this guy -- who spends most of his time in his man cave -- really want to hang out with someone so inept he leaves the cave one day, saying, "That was some sweet, sweet hangin'."? That's after he answers a question with, "Totally. Totes, magoats."
As it turns out, yes. Peter is so endearingly clumsy in trying to make a best friend out of him, that you can't help but cheer him on.
There's never any doubt about where this platonic love story is headed, but that doesn't make the trip any less enjoyable. Should you spend money on I Love You, Man? Totes, magoats. See it.
