I guess the first movie was just them getting hunted, even though it takes a good length of the movie for the Predator to get in, it is probably why Predators fits more as it just them stuck in the jungle being hunted. But in comparison to the first the Yautja gett involved quicker, and we got more information over just an old legend and apparently mud being the bane of advanced technology.
I can't hate the second one, though it is not the straight up horror chaser we got more from the Yautja's perspective, like what targets it went after, the ritual, what it wouldn't attack (I like the part we see it look at the boy or see the woman pregnant, plus I think I prefer the end of the second where the clan respect the protaganist for winning.
As for the third, it was good as it built on what I knew about the Yautja already, but went beyond throwing them in some jungle and put them on another planet, kind of that that there was no hope, might I say that the characters also felt varried and larger, I missed the twist though, should have seen it coming. But it was also interesting that they put in the Feral or Super Predators, and even compared it to a jungle dweller, kiond of made the honor of the regullar types a blessing.
