I reckon there aren't too many comic book fans on this forum and if there are, I don't know how many are into Garth Ennis stories.

There wasn't a whole lot to go off by this trailer, but I thought they did a good job characterizing Jesse (the main character, i.e. the eponymous "Preacher"). I'll admit, the accent threw me. I know he grew up in Lousiana and the story starts off in Texas IIRC, but I never really thought about him having a southern accent.
