Pretty much any Super Hero movie I'm likely go see, except Batman. I've gotten tired of being disappointed so I wait to see those on DVD. We have a giant TV and also a projector (a really good friend gifted it to us when he upgraded) so to make me drag myself out to a theater it's got to be worth seeing.

I like movies where stuff blows up (action) Die Hard, Raiders of the Lost Ark, James Bond

or there's a fight in a tea house (kung fu) anything with Yuen Biao, Jacki Chan or Sammo Hung in it.. and some others

or aliens, space ships, orcs, dragons or time travel (science fiction/fantasy) Star Wars, Close Encounters, the Hobbit/Fellowship of the Ring

And also movies that make me laugh. Ghostbusters, Happy Gilmore, Despicable Me
