Cool concept - flawed execution. Sure, the thing is shot wonderfully, and the effects are top notch, so if that's what you're looking for, you'll be properly satisfied. The story, though, is deeply flawed in keeping with both the Alien and Predator story "facts". For instance, Alien blood is, by now, well known to be highly acidic, and this is shown when one of the Predators uses his wristblades to cut the Alien, and his wristblades melt. Not more than a few minutes later, the same Predator chops the head off of another Alien, and absolutely NOTHING happens to the blade, let alone the fact that not a DROP of acid comes out of the Alien. And that's just ONE example, and believe me, there are tons of inconsistancies in logic, story arc, and "lore" - too many to get into here and now. Sorry, fanboys...I think they could have done better. Fun, but not enough.
