18. 'Nick & Norah's Infinite Playlist'
A sweet and nerdy coming-of-age tale featuring Michael Cera and Kat Dennings, an unlikely duo who undergo a series of drunken adventures involving one ex-girlfriend, one missing friend, and a whole lot of live music. (It is an infinite playlist, after all.) But the music is pretty much the best thing this film has going for it. Otherwise, it's essentially a human scavenger hunt — for unattainably attractive ex-girlfriends! For pretend boyfriends! For drunk and overly stupid friends! Sorry not sorry, Nick and Norah.
