Even if people don't want more Ridley Scott I think many other directors would be a far better choice than Blomkamp.
I want to see fresh ideas and new characters not digging up the past to see an inevitably lesser version of what we've already seen.
That doesn't mean no marines or drop ships, you can do all that without raising the dead, again.
It could be set in the late 2100's-2200s where the bulk of the series takes place (Excluding Ridlien: Davidnantmetheus), bring back the iconic human aspects of the franchise, such as the USCMC, Gateway Station, Fiorina, etc. I have a completed screenplay that encapsulates the original trilogy, yes - it does feature the Ripley family, but they could easily be substituted with original characters and personalities that already exist in the story in major roles as is. Could easily have a new Grizzled Marine who has spent his days fighting pirates and enemy governments/armies (or even Weyland-Yutani), but the main crux of the story is on a re-imagining of the Xenomorph that postulates there are many different species of Xenomorph that exist throughout the universe (and more importantly that doesn't look like the head of the original was copypasta'd onto the body of a flayed rabbit) and the crew of a dingy, retro-industrial backward-engineered military ship (that is almost literally a power station
in space) happen to run across perhaps the worst of them all. Again, could be entirely original characters. The crux of it is on the atmosphere and central antagonist of the plot (I'll have a teaser trailer mockup for the film up on Kickstarter and IndyGogo Monday...), and I'd recommend Jennifer Kent (she director-debuted The Babadook
, watch it, great horror film), but it'll probably end up being a fan-film, (but I'm really
shooting for 'indy canon/non-canon spinoff').
