I'm not saying that, I'm just responding to your specific criticism that the alien lifecyle we got doesn't work because it's not the alien life cycle you wanted. Don't confuse the two.

From where I'm standing the film works just fine as a film. As I said, it doesn't have anything missing that couldn't be said about Blade Runner. And like Blade Runner, it would be in some way nicer if the characters were more realistic and relateable like they were in Alien, I miss Parker and Brett, just like I miss their equivalents being absent from Blade Runner. But, like Blade Runner, it's not the same kind of movie as Alien and works fine without that element being there as strongly. It has other goals in mind.

Also, this isn't like comparing the PT to OT. Those are a continuous saga, and one is a direct prequel to the other. This is not a direct prequel, nor part of a saga, and barely classifies as even taking place in the same universe as Alien, which was the point I was making about expectations. As I said, take it for what it is, and not what you wished it was. You'll find a very original and stimulating movie is in there underneath all the confusing "is it or isn't it?" Alien connections.

Once you get over that confusion and just accept the film on its own terms you don't have to worry about whether it works as an Alien film because it doesn't have to, it's not Alien Zero it's just Prometheus. And I think once you cease having that backlash about it not working as Alien Zero you won't be harsh on the film compared to other movies where you would let the same sort of things pass (again, Blade Runner being a great example).
