I think I'm one of the few who actually enjoy the film as is, Although I do see it as flawed. But then It might be fun to view the story in a different way.
I'm all for tying it a bit closer to the games as well, That's one of the things I've looked into, Using more familiar sound effects etc.
I'm working on a test with that Shot above for [Anaglyph] 3d [Red / Cyan glasses]. It's sorta looking good although it may not be a great shot to try cuz the hallway seems a little soft / blurred where it's better to have nice crisp details for that sort of thing, for your eyes to focus on.
