It was a nice trailer. Good atmo and action, Ill agree about the adult aliens though, kind of wank in terms of them being effective. I especially dislike the alien who jumped onto the back of that marine to kill him, the marine should have been knocked completely down.
Face hugging was sweet.
Flame thrower scene lighting all the aliens coming at them was sweet.
Queen killing the marine, and the marine dropping the grenade thus causing it to detonate was sweet - also very much an alien 3 moment
overall 8/10
