This film has a lot going for it - the unexpected blend of gory action, bleak tone, two excellent leads, eccentric humour, and an engaging score. Indie-favorite Macon Blair's writing and direction are first-rate - the vibe reminds you of frequent-collaborator Jeremy Saulnier's style, but with added quirks. Blair exhibits splendid control over the film's tonality and pacing. Melanie Lynskey (as depressed nursing assistant Ruth) and Elijah Wood (as Tony, her neighbour with anger issues) deliver delicious performances. The writing builds Ruth up well - her internal angst and rage are justified - once the frustration levels reach breaking point, she goes on a vigilante-like rampage alongside Tony whose bizarre antics (and weapons) will definitely make you LOL. The final shot is a thing of beauty as well, and I smiled hard for it!
