Becareful what you wish for! Agreed. Like Kubrick's The Shining, or 2001 and the Monolith, the Space Jockey works better if it remains a mystery. Even though "Predators" doesn't rise to that level, Nimród Antal got it right in my opinion for wanting his mysteries to remain mysteries, even now. Because when you reveal those mysteries, instead of fascinating posts with wild imaginations where fans theorize where the Alien Xenomorph came from or what the Xenomorph is or represents, if it's some sort of space cancer or what have you, now we have David created them. That's it. And once you have those answers, suddenly the universe feels quite a lot smaller.
