Yeah, I was never much for that look either, but I suppose we'll have to bear with it, it's only a very minor cosmetical aspect, & I'm sure the overall alien will look quite similar to the classic style once we have seen it in the film. At least the warriors are making their return, I always found them to be the creepiest alien form in the series, they had an almost feral, animalistic style about them in Aliens, the way they would twitch & shudder while exposing their gaping maw was enough to send a chill down your spine.
The predator also looks great, the style harkening back to the excellent design from the second movie, with many modifications. It looks like the creatures will be adopting their unique tribal hunter style from the Predator movies once again for AVP2, which I am absolutely thrilled about. The predators in the original AVP were like massive, armour plated walking tanks, which was the complete opposite of what their species is & stands for in my opinion. I am glad that the creatures seem to be getting back into the great style they once had. On top of this, Ian Whyte has claimed that the predators in this movie will be much more seasoned, veteran hunters, which should definitely make things more interesting.
