I've only seen it once, but really only remember Tusks in one scene (where he could be seen doing something besides standing around) and that was when he exploded. Same for Falconer, only one real fight scene where we get to see him move, and then he's toast. You guys remember others that I missed? I know they were cloaked in a few, but I don't consider those to count.
The classic fight was, I think, not very good. It was entertaining at parts, but felk like T-Rex vs. Spinosaurus in JP3, basically just "the old Predator < my cool new Predator!" I will fix it, all will be right, my children.
