The fact they even considered that ridiculous human-clothes wearing abomination makes me think the people behind this movie just see the Predator as some generic man-in-a-suit monster, which they can strap any ridiculous plot contrivance on to.
It's the same thing with the 'Upgrade' - because to them the Predator is just some dumb movie monster, their logic is you have to keep making monsters bigger to keep them scary and impressive.
With each movie we seem to move further and further away from the original, simple but great premise: An alien hunter who visits planets to hunt dangerous creatures for sport.
