I don't really have a favorite, but the ones that are up there are the Harry Potter series, LOTR, and hunger games. Speaking of which, Catching Fire, the second hunger games, is supposed to come out thanksgiving 2013
Let's see...Definitely Professor Layton and the Eternal Diva, the Pikmin short movies are a new fav, Dobutsu no mori was pretty cool, the Chronicles of Narnia movies stand as favorites for sure, and I really liked Disney's Tarzan when I was little. I've always loved pretty much every single scooby-doo movie (EXCEPT zombie island), and Justin and the knights of valor is also a new fav for me.
And...that pretty much sums up all my favorite movies from the ones I can think of from the top of my head.
