"Who is she supposed to be?"
Consistently charming, devoted to the laugh, and not the raunchy. Never did I feel that it was going for a gag beyond the natural state of the story. Olivia Wilde allows the ensemble and scenario to flourish via fully-realized characters, and Kaitlyn Dever and Beanie Feldstein are fucking superstars. Not much else to say about it! It's really good, folks!
