Out of the series...
 
What is your favorite 'LOTR' movie?
I've never seen any Lord of the Rings films. I will eventually, but they're the kind of films where I'd like to read the books first - like Harry Potter. With that series, I read the books before seeing the film up until the fourth, and the experience while viewing it was horrible. I felt as if I was committing adultery.  
 
What is your favorite 'Star Wars' movie?
 Return of the Jedi. It is a great conclusion to a fantastic trilogy that makes me feel all warm and fuzzy inside.
What is your favorite 'Back to the Future' movie?
I... may have seen a Back to the Future film when I was much younger... but I hardly remember it. Can I just choose the ride at Universal? That was amazing!
What is your favorite 'Batman' movie?
Out of the Burton-started time line, I'd have to say Batman. Overall, though? The Dark Knight. 
What is your favorite 'Star Trek' movie?
Star Trek (2009). It's the only 'Trek' movie I've seen, and I don't mind keeping it that way. I have seen plenty episodes of the classic series, though, and if the other films were much like those, well, I know I made the right choice.
What is your favorite 'Halloween' movie?
Easily John Carpenter's Halloween. I like the sequel, enjoy the fourth enough and respect H:20, but you can not beat the original first. It's a simple-yet-intense classic that still scares me.
