From the looks of things, the casting of Josh Brolin was the ONLY thing they got right. Early reviews are making a lot of Wild, Wild West comparisons.
It's especially annoying as the earlier comics before there was much supernatural going on often had pretty good basic stories and entertaining action. They could have made a more modestly budgeted, far better film by being more faithful. Shoot it very practical, have some awesome western gunbattles and no stupid crap like horse-mounted gatling guns, and you'd have a winner. His actual origin story (his scar comes from a heated tomahawk) is also much more interesting than the extremely cliched and derivative one they're going with.
One thing I will say - apparently there was some HEAVY studio interference on this one (almost from day one), which is probably where a lot of the blame comes from.
Whatever the reasoning, it looks awful if you have read ANY of the original comics. I hate Hollywood. Would that terrorists play merry Hell with that business; the world would be the winner.
