Anything that sounds good.
Epics. Braveheart, Gladiator, The Patriot, LoTR, Gangs of New York etc.. Guy Ritchie Films, Jean Reno films, comedies, the list goes on.
Usually The Discovery Channel, History Channel, TLC, NatGeo. Anything that gives me totally useless facts to talk about.
Fantasy, Historical Fiction.
Those that help because it's the right thing to do.
