I mostly enjoyed this (spoilers)
I enjoyed the concept, setting and action sequences. I think the idea of Predators visiting Earth during different times in history is an overdue one for the franchise (although it was already touched upon in 'Aliens vs. Predator').
However, I wasn't thrilled by the dialogue in 'Prey' and the tendency of Naru to talk to herself. Her dog companion, Sarii, was a little cheesy at times, too.
I also had a minor quibble with the Predator, which was more of a warrior looking for opponents to fight rather than the hunter stealthily picking off prey that it was originally conceived as.
