'Short Term 12' is one of those small indie features that stays with you in a big way. It's only 96 minutes long, a modest production set in a foster-care facility for troubled teens. Yet Destin Cretton's direction and Brie Larson's performance elevate the film to, well, one of the year's very best. Ms. Larson is almost a sure thing for not getting an Oscar-this year's competition is unusually fierce-but do catch up with her portrayal of Grace, a 20-something supervisor who is far from untroubled in her own life.
