There was also a new weapon, there were predators fighting eachother, it was happening on a different planet, there was a crashed ship of unknown origin, there was a human dressed in predator tech, there was a one on one fight with blades between a human and a predator, there was an unknown prey creature - and that's only what i remember from the blurry movie i've seen. Considering that, it is impossible for the movie to be more than 30% like Predator.
