When John McTiernan's Predator came out in 1987, it started a major shift in sci-fi action movies. The main villain, The Yautja, was one of the more terrifying creatures put on screen at the time. A true horror movie filled with plenty of action. Through Predators many sequels and reboots, it seems our main villain has become less and less about actual horror moments and more about big action set pieces. Predator has long moved on from it's horror roots, but that might be it's biggest problem.
