I'm pretty sure most (if not, all) the members here have seen al the alien and predator movies. What you may have also noticed is that every movie reveals a little more aout each creature.
In Alien, we learned about the alien's life cycle and apperance. In Aliens, we learned about the alien hive system and the queen alien. In Alien3, we learned about about the aliens ability to absorb it's host's DNA. Finally, though Alien Rez did not reallt give much info on the actual aliens, it did show us the Newborn.
Form Predator, learned about the basic weaponary and habits of the predator. In Predator 2, we learned about a wider variety of predator weapons. Finally, in AvP, we learned about the predator's blooding ritual.
So my question is what do you think AvP2 will teach us about the aliens or predators? Will it continue on the alien's DNA abilities, or the predato's weaponary, or what?
*sigh* If only I was witty enough to think of something to say here.
