I saw it Tuesday, and it was better than I'd expected. I sort of agree on the convaluted ending, though. This film paid a fair amount of homage to Predator, which made it a lot more enjoyable to me.
...and what was wrong with Predator 2?
Hidden/Spoiler:
The fact that they didn't make it doesn't bother me. I actually like it when a film does something you don't expect, like this. You'd expect those two to be the BA characters, and steal the show. The way this turned out leaves you with a sense of uncertainty, which is what you need for a film like this to work. You don't want people thinking, even subconsciously, that Machete and Morpheus are going to kick Pred buttocks.
Saw this movie thuesday, and i didnt like it.
I think they should stop making predator movies its just not the same anymore.
Well at least thats my opinion, no disrespect to people who enjoyed it.
