If they're truly going to kill off all the engineers, , I don't see how they could squeeze two more movies out of this story.
My concern is that the very literal prequelization approach evident in elements of this film and Ridley's recent comments about future direction is going to lead us down the road to the Thing
prequel, where you ended up seeing how every little bit happened right down to an axe in the door or a frozen guy with slashed wrists, no matter the contrivance to get there.
I just don't feel this franchise or these monsters need that, I feel it diminishes them. I felt the meta-prequel/sequel approach Prometheus
had, for all its faults, which led to a wider canvas and left the alien and the backstory of the first film mostly undiluted, was best.
I know I seem relentlessly down on the larger story direction and that's because I honestly am. But I also feel AC looks gorgeous style-wise and I expect it to be a fun and scary movie.
