I still maintain that the opening in Mexico and the lab breakout scene are comfortably the best bits of Predator action we've had since Predator 2. The moment when the Predator's face is revealed by the blood pouring down onto it was incredible.
I mostly agree, except for two tiny things.
1 - The CG effect of the face reveal was really meh. But the idea is marvelous. Better idea than everything we got in all AVP/AVPR/Predators
2 - The lab breakout is one helluva fun scene, but the predator complexion stand out so much in this mostly white immaculate environment, that it highlights the fact that this is a guy in a suit. The pred was never created to be in another environment than the jungle initially, that's why it's a bit of a visual problem for me.
