Truthfully, I'm most anxious to the Batman Trilogy. They did such a wonderful job on the Dark Knight. Their version of Joker is still giving me Goosebumps of excitement. But I'm a little scared of the tradition that when everything is put to an end, the director somehow screw it up. I hope Nolan won't do that.
I picked Iron Man 3 eventually. Less dark. and just plain cool. and the only reason it won was it got mech, and because I'm an incurable mech-addict. Which would've put Transformer 3 on the top of the list.
