In true geekoid fashion, I'd have to say that LotR and Star Wars (the original trilogy, not the second half-assed ones) are my favorites. Other than that, there's very little I don't like... and yes, that does include really campy, cheesy B-flicks (absolutely love 'em) like Bubba Ho-Tep or Jack Frost.
Battlestar Galactica and Stargate! I also love pretty much anything on the Food Network, NHL Hockey, Dirty Jobs, and Mythbusters.
