I thought the new predators looked pretty good, recognisable, but different, just as there's a difference between races in the human species, there are differences between races in the predators.
I think the movie really brought out the theory of Darwinian evolution (Any creationists here, hold the hate). With the new predators actually being more suited to hunting than the original, which was intended to make them frightening (I didn't find them frightening, I don't tend to find sci-fi creatures frightening).
As for the fish-head of the new predators, if you look at all the different races on Earth, you'll see slight differences in head shape/facial structure and so on. So the different, creepy appearance of the new predator really makes sense to me, and I hold my belief that it was a very good idea.
