"So our idea was that their planet is dying. And so they've decided to take what previously was explored, which is to dope up creatures with the DNA of other types of predators from alien worlds and create new targets for their hunt. But now they realized, well, hey, we need maybe to upgrade ourselves just to survive. And then they go to themselves, well, hey, earth is warming up. We like a warm environment. Maybe we should move in. So the premise of the movie is that in the third act was these two predators come aboard the ship and everybody's freaking out and the predators actually want to communicate. They want to say, "Hey, we've got a problem, you have a problem. Maybe we should team up." "
This whole thing of "this happens...and that happens...and this happens" is why the movie failed. This whole idea was garbage.
