Doesn't look too good in my opinion, I think I'll get tired of the first person thing pretty quick and it doesn't seem like there's an interesting story in there. I've never really liked FPS games and it seems like it will just be like watching someone play one.
I admit that they take about 15-20 minutes into the movie to adjust, which is annoying as hell, but this looks pretty sick. I can understand why you would be a little resistant if you don't like FPS too.
Not into the gratuitously violent movies as much as I used to be. It's got to have a good story for me to enjoy it. This looks way overboard on the violence...
