Is it better than the first 2? No, is it better than every other? Yes! The bad reviews are missing the point and just dislike because it's not what the originals were. the predator in this is young, possibly learning how to hunt on other worlds, the main character has learnt how to hunt on her own but learnt to fight as she is obviously hot headed and independent so forever getting into scrapes with the older guys.
I like the way the predator moves, I like the not too hi-tech hunting gear, not the biggest fan of its face (should of stuck with the original face) but all in all not bad.
