Well, not to be annoying, but they don't have eyes we know of, and even if they have some method of seeing other then eyesight, I think its possible it looks like what it was in A3, there is nothing in the film to say thats just a camera angle
I mean, we have the predator POV shots, and technically those are camera angles, but I'm smart enough to realise that its showing how they see things
and I've always gotten that impression from Alien 3, even if they don't have eyes, I think those POV shots are POV shots, the alien's POV, not the alien's camera angle
