Shows, definitely Doctor Who, been enjoying Once Upon a Time, Teen Titans of course. I don't watch too many shows, though.
Movies, definitely Lord of the Rings, the Hobbit, anything in the Marvel series as well.
I like all sorts of music, anything with a beat, though I have a particular preference toward country and the whole nightcore/trance/electronic/techno genre, though rock and pop are good at times.
2. A good book / my Kindle
3. My Xbox
4. My collection of D&D/Pathfinder books
5. My 3DS
6. My bag o' dice.
Worth noting that friends, family, and the like aren't things and therefore don't belong on this list.
