With Youth In Revolt, Cera does prove that he can go outside of his usual stuttering-geek wheelhouse, and most of the scenes with him in character as Francois are hilarious. Cera's also surrounded by an able supporting cast, including Zach Galifianakis, Justin Long, Ray Liotta, Steve Buscemi and the always-game Fred Willard, and they're all doing solid, funny work.
The main problem that the movie can't string together enough quirky, vaguely funny scenes to overcome is the fact that the character of Sheeni (who, as the girl Nick is pursuing, is sort of the primary driver of the plot) is sort of horrible. She's pretentious, manipulative and appears to take great pleasure in messing with Nick, always happy to mention her mysterious, apparently perfect boyfriend, Troy, to make Nick feel jealous and inadequate. Which, considering every action our hero takes is in pursuit of her, ends up undermining the movie. I was sort of amused for much of Youth In Revolt's running time, but I never actually cared about Nick or whether or not he won Sheeni. Many of the characters are funny and eccentric, but none of them are what I'd call likeable or engaging, so I never cared about what happened to any of them. And I certainly didn't care if Nick ended up with Sheeni.
Youth In Revolt exists halfway between something close to reality and the absurd fantasy-world of movies by filmmakers like Wes Anderson and Napoleon Dynamite's Jared Hess. Almost every character in the movie except for Nick has a weird eccentricity that feels manufactured and put-on, with the exceptions of Nick's dual father figures of his actual father (Buscemi) and his mom's boyfriend (Galifianakis), who are both blue-collar slobs that the movie really seems to look down on.There's some funny scenes in Youth In Revolt, but on the whole there's little more going on than forced quirkiness. Despite its flirtation with indie-film pretension, Youth In Revolt has nothing to say about youth or rebellion or puberty beyond "teenagers want to get laid." Bravo.
