True Adolescents: 3 of 5 stars

Mark Duplass is sort of the indie film answer to Jack Black, Jason Segel or Seann William Scott. Over 30 and at his best playing guys who refuse to grow up, the former Puffy Chair star is right at home in True Adolescents, a hit-or-miss Craig Johnson comedy.

Sam (Duplass) is 34, still in a band, still hoping to get that break in the once-hot “scene” in Seattle. We meet him as he’s playing to an audience of six, and his girlfriend is dumping him. No job, no interest in finding one, no worries. There’s always his too-supportive aunt (Melissa Leo of Frozen River). But crashing at her house means Sam needs to pitch in when her ex-husband bails on a camping trip with her hostile, angry son (Bret Loehr) and his best friend (Carr Thompson).

Rocker-boy Sam drags the lads into the deep forest for a little bonding and camping. They’re great at reminding him that he isn’t that cool and that he has no clue about camping. And he’s just as quick to poke their sore spots.

Predictable, but not as predictable as you’d think, True Adolescents is the best Duplass showcase yet, even if it is School of Rock Meets Meatballs.

Screening at: 9:30 p.m. Saturday, March 28, Enzian; 2 p.m. Wednesday, April 1, Regal.
