Scott: I think the Beast is almost run out
Then just step the hell back and let someone who still has a passion for this franchise and creature, direct a movie fans really want to see and deserve. Then maybe people don't have to go through philosophical bullshit and Alien-Puking androids with a Wagner-fetish. This is some high quality Strause-Level bullshit.
Canceling the Alien for the next one and bringing in new (yet lame) creatures won't make the movie any better if your story is shit from the start. If you don't have trust in the creature (which is the core of the franchise) then why make a sequel/prequel? Make something new, but i understand... you can't cash in on the fans then. They don't even have a point up until now, we still don't know how the derelict got there.
I thought Covenant was a step into the right direction for the franchise, going back to the horror elements that were sorely missed from Prometheus, but having seen two big budget movies now i think Alien works better in smaller yet more powerful and inventive films.
I think they should really just totally reboot the franchise, set it after all the Alien films with brand new characters (No Ripley clones please), you can have the classic Alien and new creatures and make it all much more interesting.
