I'm all for it, we had countless "simple" Sequels, and while they all work as contained stories, i would actually like to have one movie connected to the events of the first one.
I love Predator 2, but it would have been awesome if it would have opened with the guys in suits investigating the place with the dust and all. One of them stumbles across this Piece of metal, dusting it off it reveals the half burned mask of the original Predator, staring right in the camera *boom* Title comes in.
I would love them to really connect it to the Events in the first movie, what happend after this? Did they found something? What's the aftermath of this incident? There is much potential.
Good News for me.
