Ah, well there are quite a few things I like... @_@ and that list is way too long to type out frankly, so I will give the basic mainstream rundown and a few less common. To start, obviously Pokémon and Being Human.
Video Games: Assassin's Creed, Halo, Mario franchise, Zelda, Skyrim, Mass Effect, and I have a small obsession with Sims.
TV Shows: Big Bang Theory, Supernatural, Downton Abbey, Elementary, Game of Thrones, Teen Wolf, various dramas and comedies.
Movies: Disney/Pixar franchise (including Avengers), X-Men, Terminator, Dreamwork's HTTYD, Star Wars, Star Trek, various dramas, animated films, and action.
Books: Harry Potter, Inheritance Cycle, The Count of Monte Cristo, Anne McCaffrey novels, Hunger Games (though the third disappointed me), etc.
Anime: Full Metal Alchemist, Digimon, Tiger and Bunny, and Tales of the Abyss.
I think I covered most of it. xD What about yourself? What kind of things you are interested in?
