I liked Superman a lot but I will admit the last half was a bit much (also, I hate Kevin Costner).
Pacific Rim was a lot of fun to watch but one shouldn't watch that one for deep character development.
300 I loved but I'm a big Frank Miller fan and you should know what you're getting into before watching that one. Same for Sin City. I heard people complaing about the violence afterwards but with a name like Sin City.....yeah.
A fun one I just watched was Kick-Ass 2. I was rolling with laughter during the whole thing.
I'm almost liking TV shows more now for depth of character. When Anthony Hopkins emails Bryan Cranston to tell him his Walter White was the best acting he's ever seen, made me go on a Breaking Bad marathon. Some other TV shows just seem more rewarding than a 2 hour movie.
