The indie comedy "Nobody," filmed in Minneapolis last year with a largely local cast and crew, may well be remembered as Sam Rosen's starring debut. It's not likely to be remembered for much else. Pleasant, lightweight and inoffensive, it's youth comedy at its most generic.

Rosen stars as Lindeman, a sculptor fretting over his graduation project for the Minneapolis College of Art and Design. He has to make something meaningful from a two-ton block of granite. Afflicted with a virulent case of Senior Slump, he can't decide where to chisel. And given his realization that he's not a genius, he wonders why he should even try.

The problem, his friends decide, is a form of identity crisis. To help him find his muse, they lead him through goth and gay culture, invite him on an anything-goes weekend getaway where S'Mores trigger adventurous extracurricular activities, and recruit him into vegetarian boycotts outside Porky's drive-in restaurant. The vignettes are broadly comic clichés that might play better with high schoolers than grad students. At what age is a protester in a radish costume funny?

The art school setting is a gallery of familiar types (dour wiccan, icky-cute lovebirds, jaded intellectual). While most of the performers are attractive and amiable, few make an enduring impression. Only veteran character actor Mark Margolis scores as a lecherous lecturer who decries the misogyny of major artists because "chicks dig it."

Rosen holds the screen nicely, but he's too good-looking and self-confident to convince as the diffident, dateless Lindeman. The story requires him to moon after Lelle (Helena Mattson, playing "the most beautiful girl in Minnesota," a subtitle informs us), who doesn't register his existence. Unlikely. He has several scenes with a therapist, but he isn't persuasive as a lost soul. With the presence of a romantic leading man, Rosen is awkwardly shoehorned into the lovelorn-sad-sack role.

In his feature directing debut, Rob Perez -- writer of the Josh Hartnett celibacy comedy "40 Days and 40 Nights" -- works capably within the limitations of a thrift-shop budget. The technical credits are solid, and the city looks lovely throughout the theater of seasons. Overall, it's as if someone bottled 85 minutes of Minnesota Nice.
