When the trailers arrive, I half expected Hansel & Gretel to team up with some good witches to "prove" not all of them were bad. Not that I am disappointed by the lack of the obvious trope, but I guess an obvious one would at least proven that they put a little effort to separate themselves from the simple premise.
Fighting monsters with steampunk weapons is a nice idea, but it was fresh in Van Helsing and Wild Wild West and not even that could save them. At this point, I kind of expect any monster action movie set in previous centuries to have some anachronistic devices just to make them interesting; to the point its almost cliche too.
And Bob, isn't it a little too easy criticism to say a movie about witch hunters is misogynist because the villains are witches? In popular culture, all witches are women... Its like accusing some videogame set on Africa of racism because most villains are black. I guess it hit a nerve with his Bostonian background, but I still think you are reading too much between lines.
I don't mind the choice of JJ for Star Wars. Its the obvious nerd choice outside of Whedon, but I think he can do pretty decent jobs. Sure, Star Trek had little in terms of science fiction, but it was a decent action flick, same as MI3; and I really liked Cloverfield.
