The Dark Knight
The coolest movie of all time! I'm not kidding, this is my vote for the coolest movie ever. Masterful in every way - the story, the directing, Heath Ledger as Joker, and oh yeah - Batman. All I can say is thank God superhero movies aren't for kids any more.

Cloverfield
Although not the best movie, the effect they created by using the home video angle was classic. I still remember the first time I saw the monster, it was like watching your buddy's home movie at his bar-b-que and then seeing a monster on the film. Great effect.

Iron Man
Although The Dark Knight is the best superhero movie of all time, I think Iron Man is the most fun. The role of Iron Man and Tony Stark could not have been better cast than Robert Downey Jr. Funny, amazing effects, great story and just overall so cool.

Hancock
This is another movie I had great exceptions for and was let down a little. They made Hancock such an oaf that it was very annoying after a while, especially when you have someone as electric as Will Smith just waiting to bring the character to life. And I didn't think that ever really happened. But that being said I liked the story and overall it was fun to watch.

RocknRolla
You can't have have a cool movie list without adding the Guy Ritchie movie from that year if there is one. Critics didn't love it, but if there was one thing this movie was oozing with it was cool.
