I'd have to say my favorite was Up, it was a quaint movie with a nice plot, a small yet interesting amount of characters, and is great for a general audience to view. But I do really like other movies such as the Back to the Future Trilogy, Terminator 2, Schindler's List, there's a lot of other movies that fairly entertained me. I feel like Up can be shown to anyone of any audience though.
Sounds like you are 9 mate
it's not like your age determines what movies you like
besides i've seen your insult topic
