It made sense and worked well for a more savage, primitive, 300 years prior to Anytime's rendition of a Predator. IE "Feral"
Evolutionary humans and humans in different areas of our planet look very different.
Feral is still identifiably a Predator but unique and new with a twist.
Unlike post Predator 2 wannabe, rubbery, poor man Stan Winston imitations of the Jungle and City Hunter we've seen from AvP to The Predator.
It is a more unique execution of what some of the more modern sequels attempted to be. Plus it was filmed great, dark, wet and realistic and not rubbery or costume like. And left me wanting more. In combination with his portrayal being much more in line with the menacing solo honorable hunter like the creature was from the first two films.
I get not liking it, but it's still identifiably the character, while twisting it just enough to feel new so the audiences isn't desensitized to the character visually since they have so much familiarity with it by this point.
