Agreed on the Pyramid. That was actually a good idea. However, it would work better on a alien planet, where some future archeologists find it. Mind you, still cheesy B-movie territory, but still works better than Antarctica. Blooding and pack-hunting is also still a good idea. I'm ok with eggs and Chestbursters, but no Queen please. Kinda done with Queens everywhere.
PredAlien..... Not sure. I watch AvP:R once every two years or so. Sometimes I like the design and concept, sometimes I don't. I'm still not sure about the idea of the Xenomorph taking qualities from the hosts. In Alien3 the Xeno did the same, but it was still a straight up Xeno, but with a few slight differences. The PredAlien is much more a hybrid, and I'm just not sure on this concept.
The idea of the YoungBloods needing to earn the more advanced weaponry was also something I liked. Things like the shurikens or extra long wristblades were a bit too much though. Bit comicbooky/fanwanky.
