My god, I see the Pilot!!! They better not ruin it by putting in non canon giant bald men.
In fear of starting another 'canon' discussion I tentatively ask what makes Prometheus not canon?
1. Ruining the Space Jockey.
2. Crap Dialogue.
3. Spiffy Mr. Clean Ship.
4. Bringing in Religion into it. (Space Jockey Jesus, WTF? There are Christian fans of the Alien movies yah know)
5. Technology that is more advanced then the latter movies. Shouldn't the shit we see in Prometheus be standard issue by ALIENS?
6. Idiotic Characters.
7. Plot holes.
8. Turning the ALIEN universe from a dead nihilistic space full of mystery to something on the bordering of Star Trek.
Honestly putting Predators stuff would be just as bad as putting Prometheus stuff in here. Prometheus can stay in it's singular canon world, away from the ALIEN universe. Just like the AVP and Predator universe.
