written and directed by Lynn Shelton
by Angelo Muredda Lynn Shelton tends to swim in the deep end of the mumblecore pool. More improvisatory than the scripted films of the Duplass brothers (despite their overlap in casting), her work, in an odd sort of way, is probably closer in spirit to Joe Swanberg's. Swanberg's shabbier DIY aesthetic masks the heady nature of his projects, which explore the same three or four ideas about modern relationships in forms as disparate as the anthology film (Autoerotic) and the meta-slasher (Silver Bullets). In Humpday, Shelton nicely marries her own high concept--to make a movie about hetero male insecurity writ large--with a pair of naturalistic performances that elude Swanberg's scratchier efforts. Her M.O. appears to be to let her actors fumble through a convoluted situation that, on the strength of their characterizations, never feels as unnatural as it probably should.
