The posters made it look like the the Joseph Gordon-Hewitt character was carrying around some kind of bad ass Doom like plasma weapon.
Then I saw a trailer and found it was just a regular shotgun. Completely turned me off from watching the movie.
It wasn't even a regular shotgun, a shot gun would have been an IMPROVEMENT, what he had was a blunderbuss.
For me, and for many of us, the future is now in the past.
