It was a situation where you had to accept the things as they were. The first one ended having just gotten off of Earth, and then the predalien pops out. You can't just ignore something as cool as that. Unfortunately, you have to deal with the cool thing in a blah place. I certainly wouldn't want to see a cataclysmic battle of the species slugged out in my home town. That stuff is for creepy foreign planets or spaceships. But since this movie was towing a heavy allegory of cleaning up a mess left behind, we have to deal. I still liked the movie. It was very entertaining, in my opinion. I'm sure it won't garner any awards of praise, but I left the theater feeling better for having seen it.
