Sure, but his body language is also more monstrous than most Predators. He has a tendency to just walk up to enemies rather than attack from a vantage point. And then there's his face.
No single change is an issue, and no single change is inexplicable.
But combined, the final result is something that feels more like a high tech Jason than a Predator. That might be a perfectly valid thing for a Predator to be, but to me, it's not what I'm here for.
Is the same to me as the AvPR Aliens compared to the originals. Sure they run on walls and ambush and what have you, but watch that movie side by side with the originals and tell me you don't see a remarkable difference.
