...in L.A. - get it? New York artist-girl (a highly sexualized Olivia Thirlby) camps out in the Silver Lake home of a Hollywood sound engineer, his wife, and their kids (one shared, one step). Almost everyone proceeds to get the itch: hubby for artist, wife's therapy patient for wife, daughter for hubby's assistant, hubby's assistant for artist, Italian teacher for daughter, etc. A fine cast (John Krasinski, playing it straight; Rosemarie DeWitt, playing it cool), a script blessed with some tart exchanges about sexual dynamics, and a pleasingly small scale are underserved by the story, which is thin, observational without being insightful, and awkwardly padded. 2012.
