I think you pretty much covered it. Any way you can hide some of the lesser actors by cutting more dialogue. Like that one guy from AVP, who understood all of the symbols in the temple. I would rather he be silent, if not gone from the story. He is basically saying shit that is going to happen anyway. Maybe it would be more mysterious if he didn't tell us what was going on.
Of course it has been quite some time since I last saw the movie.
