Face to face is the only way to get a decent read on people anyways so this is really about discovering shared interests and if someone says terribly inappropriate things.
movies, might say judge dredd the original then the star wars OT then maybe perks of being a wallflower, interview with a vampire, most kevin smith movies minus chasing amy, old boy, god bless america and the beach all make a small dent in all the movies i think are awesome
shows would start with anime (general i know but there are way to many but cowboy bebop and trigun must be mentioned), game of thrones, then maybe dexter, ninja warrior, always sunny in Philadelphia, freaks and geeks, The Tick, wilfred and dr who of course
music smashing pumpkins, the tiny, regina spektor, lianne la havas, portishead, puscifer, tool, bjork, frank sinatra, johnny cash, brad paisley, the doors, postal service, modest mouse, die antword, tori amos, deltron 3030, brother ali, outkast, mos def, greydon square, immortal technique, megaran, talib kweli, atmosphere,(anything on the rymesayers label) otep, iced earth, david bowie, michael jackson, trampled by turtles and im sure theres tons and tons more
food would be sushi or anything with cheese. mexican or italian are favorites so cheese enchiladas are numero uno but the comfort food aside #6 jimmy johns sub. Indian and Ethiopian food are also awesome. Anything with a kick
