It was a reasonably okay action movie, though I felt it was calling out for more quiet tension, silence and stillness as per the 1st movie.

Brody was hilarious though, I couldn't take him seriously at all, he simply cannot play an action movie star for me. Though when I stopped and thought who should have been in the role, I realised what a dearth there is of simple good old fashioned style action starts like Arnie, Stallone, Bruce, Van Damme and Lundgren in teh modern era.

The wolf/dog alien cast stuff was completely unecessary and pointless. As for the opportunity missed? Just after they had tumbled into the water, I thought for a minute that maybe the Predators were in fact humans, and that was why the old fashioned predator was strung up. I'm not sure how i'd have followed up on that, but i'm pretty sure if it had gotten to the end, everyone had died and the prdeator uncloaked and removed his mask to be humad, it'd have been pretty cool and a way to bring in a shock that was otherwise unattainable. (After all, a lot of the tension in teh 1st movie was about "what is it?". When now, we all know beforehand.)
