In defense for Jonah Hex, go see the DC Showcase animated short of the character, (AWESOME!!!
And sadly, that 10mins. short gave more JUSTICE to Jonah Hex's character than the film can hope for, obviously...) which is based on 1 of the issues in the current run/series of comics, issue 19 to be exact, by justin gray and jimmy palmiotti. Also, read said series, Jonah Hex vol. 2 #1-50.
Jonah Hex movie WASTED opportunity...
But we @least have the Jonah Hex DC Showcase to make up for that and Thomas Jane should have gotten the part! He did audition for the role before it ultimately went to josh brolin and he got to voice the character instead. But seeing it had a VERY weak and mediocre final shooting script i'd be happy w/ the dc showcase JH short anyday. They should have sticked w/ the original script which is closer to the source material...
