I grew up reading Jonah Hex, he's a great nasty character, and Brolin is a great and now choosey actor. He was worried about doing a comicbook movie after the success of No Country, but once he read the script he was sold. Megan Fox doesn't hurt either. I will not be basing any opinion on a trailer seeing as that is not a movie or a director's vision, its the marketing team. You can tell but 2 things from trailers: jack & sh1t, and Jack left town.
