I like a lot of the 80s classics, especially Ghostbusters. And many baseball movies: Mr. Baseball, Mr. 3000, Moneyball, etc.
The wife and I watch Love Actually every Christmas, along with a few other favorite Christmas movies.
I hate to admit it, but there are some silly ones I like as well, like Captain Ron, Big Trouble in Little China, and Hitch.
Another vote for Captain Ron. Quirky humor with a bit of adventure thrown in.
