I'm definitely getting a heavily The Thing and Dead Space influenced vibe from these new pics. I love both franchises so very much and would've loved to see these ugly beasties adapted to screen. I do prefer that new Neomorph render to the one we actually got. The way it's jaw extends is a lot more terrifying.
I think it was a bad desicion (on whoever's part) to give us the Alien so soon. That reveal should be kept for the last half of the final film, however many films down the road that would've been. They should've just concentrated on David, the Goo, and his attempts at creation - Pushing us closer to ALIEN.
As much as I love Covenant, I think it would've stood a better chance not having the release date pushed up so much. The post production could've maybe breathed a bit more.
