Yeah, im also not a fan of Ferals face design. Doesnt ruin the movie for me, but i dont get why they always feel the need to create a new Predator sub-species every since Predators. Now we got Classic Preds, Super Preds, Upgrade Pred, Feral Pred.
This movie wouldve worked just as well with a classic Pred. Make him look different (like the City Hunter did) and make him a bad blood, and itll new enough to feel fresh. No need to cram yet another new Pred into it.
But oh well. As i said, doesnt ruin the movie for me.
