Teen angst, divorce, raging hormones and lovesickness all crawl under the creative covers for an amusing romp in director Miguel Arteta’s Youth in Revolt. The film, which is based on C.D. Payne’s 1993 read, “Youth In Revolt: The Journals of Nick Twisp”—and its literary brothers, “Revolting Youth: The Further Journals of Nick Twisp,” and “Young and Revolting: The Continental Journals of Nick Twisp”—is a delicious dark comedy that finds its protagonist (Michael Cera in a winning role) hoping to win the affections of a nubile teen dream (Portia Doubleday as Sheeni Saunders) that he meets during a family vacation. It’s the perfect role for Cera, who has already mastered the art of playing the underdog in other films like Superbad, Nick and Norah’s Infinite Playlist and, of course, a career-making role in Juno. But here, he’s given a little more to play with creatively, mostly because the character of Nick Twisp, revered in some literary circles, is such a rich beast filled so many wild emotional undercurrents.
