Star Trek was two hours of pure fun and I enjoyed every single second of it. It was a space adventure movie and there weren't lot of those in past decade or so.
Out of the three Nolan's Batman movies, I liked the first one the most.
TDKR was just average and way too long.
Prometheus is the disappointment of the year for me, one of the worst movies I've ever seen. It was pretty to look at, but the look of it is the only positive thing I can say about the movie.
