I don't know why everyone is so pissed off with the pose.
Its pretty classic Predator to me, arms out stretched screaming to the heavens in victory.
This is the pose i'd like to have seen the P2 in.
I think he's seeing more of an "I feel pretty, oh so pretty!" than a "screaming to the heavens in victory" in this statue. Eh. Could go either way.
The Predators in AVP did behave differently than those in the original movies, though. Subtlety went out the window with that film.
