I can do my top 3 movies.
Inception - It's a fun one to watch and rewatch to see if you missed something. And to support why you think Leo is/isn't in a dream in the end.
Napoleon Dynamite - I'm not a fan of most comedy because it seems like what is/isn't funny is subjective. But this movie is funny to me.
Tron: Legacy - Graphic-wise, I think it's cool and I'd want a room in my house to look like that. And Daft Punk on the soundtrack was a great move. Waiting for a 3rd one, even if it doesn't happen until I'm 40.
