Scott Pilgrim vs. the World (2010)

Edgar Wright turns a slacker bassist's love life into a video game: to date Ramona Flowers, Scott has to defeat her seven evil exes in fights that end with on-screen scores and a shower of coins. It is twentysomething aimlessness played at maximum volume, with garage-rock gigs, cramped shared apartments and friends who roast you constantly. The rapid editing and on-screen gags reward a room paying attention, so it suits the early part of the night. Kieran Culkin's deadpan roommate Wallace is the one everyone ends up quoting.
