Until Ridley Scott kicks the bucket, or Sigourney Weaver does.
I think it's disingenuous to say that all Neill wanted was Powerloaders,
but I will say that I believe he doesn't understand the series
and that from the ideas he presented- what he did want was trite.
I think neither Scott or Blomkamp hit the nail on the head, Scott in writers he's hired or
the Alien being of the cosmic unknown inherently.
But he gets that it's an unrelenting rape monster in a world that's utterly f**ked where the company
can and will exploit you.
You can't always get a happy ending, that requires the same as in IRL- luck and perseverance.
& I think he was far closer to the mark than N.B's track record indicates (In writing, directing, concept)
N.B would've been.
