Caught Predators last night. Loud and bloody, with some really well-done scenes. It's not as genuinely suspenseful as the original, but it steers pretty well away from the truly bad characterization of some of the sequels, although one or two of the characters are overdone. Solid visuals, with only one or two bits of obvious, bad CGI. Finally, the plot (and I won't spoil it, don't worry) goes straight over into survival / outlast horror-- the characters have to deal with not only an intelligent enemy, but their environment and one another. Rodriguez doesn't do anything especially revolutionary with the series, but he does a great job of fixing what other directors have goofed up.
Also, Adrien Brody apparently put on 20+ pounds of muscle for the role, and it shows. Such a good actor, even if he's channeling Bale's Batman voice.
