Re: Which Comic Book Movie in 2013 are you most looking forward too?
I had to choose Man of Steel just because I'm more interested in what is going to be done with the reboot of Superman than I am in Iron Man and Thor's respective sequels (though I am excited for those, as well).
Also GI Joe Retaliation looked half-way decent to me (never saw the original, the trailer just did not appeal to me because it appeared to have very little to do with GI Joe. Here you have a very strong emphasis on Cobra Commander looking like Cobra Commander, The Rock looking like Roadblock, Bruce Willis looking like General Hawk, etc.)
That said I plan on seeing most of these, such as Sin City 2, The Wolverine, etc.
