I have my gripes with PREY, but I will say the main thing that gets me with Feral is the design. I just can't stand the face on that thing.
But as far as how Feral acts, I actually didn't mind. He displayed curiosity, had a very cool development going from hunting animals to hunting humans. I thought with the design aside he was one of the better Predators we've had in a while.
I didn't really like how Feral was discovering humans for the first time, since I believe predators have been hunting humans for a long time. But this could always be fan cannoned to feral being a different species of predator from a different planet, etc, etc.
With that being said one of the other things that didn't really make sense to me was how primitive ferals equipment felt. Not necessarily the weaponry but just the design. I get what they were going for, but it felt like his design was matching the time period too closely.
Personal preference, but I like the consistency between the Predators in the first few films. Probably helped that Stan Winston was still working on it.
If I really had to nitpick Feral and the interactions with the humans, maybe a little more stalking. But even then it's hard to say because this was Ferals first time encountering humans so it seemed like Feral was just letting it rip and winging it at points. Using more of a beat down approach versus stalking
