I agree that the movie is very well done. But the feeling of wondering what is the Predator and then finally seeing it is a cool looking Alien with advanced weaponry hunting for trophies just because it is part of their culture will not be able to be replicated ever again. And any other Predator movie after that will never be on that level no matter how good the script is.Not really disagreeing with your point, but I say the main reason no other predator movie will compare is that the original was peak john mctiernan. He was in God mode making that, die Hard, and red October.
I would say that the only thing that might feel refreshing is the Predator homeworld. Granted, we did see a small glimpse in AVPR, but knowing more of their culture and maybe throw female Preds...
The first Pred felt like and action version The Thing.
