Imo the Queen could be a side line monster.
* I would like to see a focus on some surviving Engineers vs. David either on the settlement planet or in deep space.
- Wouldn't the Engineers be pissed after what David did to their home planet?
- As for the monsters, within the budget (~$100 million), I'd want some battle between Engineer led monsters (Neomorphs/Deacons) vs. David's team of xenos and maybe a Queen on David's side as an added bonus.
- I'd like a return of Walter (maybe helping the Engineers; who emerges from their ship?).
- As for humans (besides a human ship which starts the movie by blundering into David), there could be some who got away from David who are hiding on the settlement planet or are in an escape pod.
* In the end I'd be happy if the Engineers (+their monsters), Walter and the surviving humans all go against David (and his xenos).
- I don't know if anyone else thinks that would work but this kind of story has been forming in my mind ever since I saw "Covenant".
