I think its a case of us looking at the Plot and Set-Up and sometimes Fans are not pleased with what is shown, but sometimes thats LIFE.... not every Alien Fan was Happy with Cameron's Queen and Bugs... but it had to be accepted as Canon. With doing a Prequel that covered the Xenomorph it could have either Gone Against the Queen/Bugs or Made it Concrete or even offered some Ambiguity towards it, so that the Queen/Bugs is just ONE Variation of the Organism.... we have yet to conclude the Prequels and its a Question of if they will give any clues to the Xenomorph Queen or not?
With the Prequels some fans were not Happy with the reveal of the Space Jockey, some thinking it should have been a Skeleton, some thinking it should have been a Mystery but ULTIMATELY it appears we are shown the Engineers as the Space Jockey, which some accept.. but maybe the SIZE is something that Bugs people!
You CANT please every Fan, and so showing us the Skeleton is maybe not a way forwards, and we have to ACCEPT it is a Space Suit... but the Occupant can be FIXED!
*A reveal of a Taller Race who may/may-not be related or look close to the Engineers or completely Alien but Humanoid/Bi-Pedal could be a Path to Try and give some Middle Ground but still connect to the Engineers (opening up another Plot.
Then we need to look at the David as Creator and some Fans are not pleased, some are really upset and i dont think many think this is GREAT! But again we cant just throw this Plot Out and Ignore it..... there is a FIX
*Having some other Race come across Davids Creation and then seeing the Potential to Harness and Evolve this to their Hubris which then reveals THEY Created the Xenomorph via Evolving Davids Creation, is maybe the way to GO.
Some fans may not be interested in the Philosophical Themes and Creation and Hubris Themes, but they have to accept that in PART this is not a part of the Prequels and a attempt to Expand the Franchise beyond Queens, Eggs, Face Huggers, Chest Bursting and Xenomorphs.
You face a tough call when trying to FIGURE what do they do, because THEY cant please everyone.. If they KILL off David like Dr Shaw, like Newt and Hicks, then whats next for the Prequels? HOW do we continue the Origins, and get to the Back Door of ALIEN?
Covenant Ship arrives at LV-426 and we arrive after David has been KILLED, or we see him Die Early on... Then Ship is Damaged or Forced to Set down on LV-426?
Does the Xenomorphs get Unleashed on the Covenant before the Ship arrives at LV-426?
Does the Ship suffer a Xenomorph Outbreak and a Escape Shuttle heads down to LV-426 but one of the Escapees is infected with a Queen Xenomorph?
How does the Derelict then come into play?
Does a Engineer Ship come after David but arrives after the events that lead to his Death and a Xenomorph Outbreak. And so do they discover the Covenant Ship (in Space or on the surface) or they discover the Escape Shuttle?
Do these Engineers get infected with a Queen Face Hugger and this Strands the Ship or it Crashes after trying to Escape?
Do the Engineers manage to discover Eggs on the Covenant or the Escape Shuttle and Attempt to take them to their Ship and become infected and then either get Stranded or Crash after trying to Escape?
WHAT other Plot could they come up with if we are too see the Covenant head to LV-426, they Kill off David Early and Engineers are also incoming but eventually get infected by a Queen Embryo or they are infected by a Normal Xenomorph but they managed to LOAD the ship up with Eggs but then WHERE/HOW did these Eggs come from?
All we would be getting is a bit of Aliens, mixed with Alien 3, a bit of Alien Resurrection mixed with AVP (replace Predators with Engineers)
Would this even please everyone? what about those WHO want the Xenomorph to be Ancient?
Covenant Crew Survive David (he is killed early) and Xenomorph Outbreak and Survivors end up going down to LV-426 and discover the Derelict and then we see more Xenomorphs unleashed only these are Engineers ones?
This really shows the LIMITATIONS to a Plot that goes to LV-426... Especially if we....
*Give David little time or none and kill him off, and pay little attention to what David does next, what becomes of his Face Hugger Embryos etc.
*Having incoming Engineers and Weyland Yutani Rock up on a Baron (or maybe) Moon where the Covenant Survivors have JUST survived Davids Xenomorphs and NOW they have gone out the Frying Pan into the Fire?
*Show the Derelict as already being there for Thousands of Years..... Worse... this is where some Engineers are awoken!
Maybe a Plot that would please the Popcorn Fanboys but would it really do any justice?
It would be just a Spoon Fed bit of a Coincidence!
Going to Origae-6 First maybe gives more options, but if we follow Plots like above but go to Origae-6 then we have to END up on LV-426 and so how does that happen?
Survivors Escape in a W-Y Ship and by chance happen to end up on LV-426 and discover the Derelict already there.... Que a repeat Running and Shooting Aliens again!
Survivors are Captured by Engineers and taken to LV-426... but WHY? and then reveal these Engineers take them down to where they have the Crashed Derelict as those Xenomorphs need HOSTS?
As it would make No Sense to take them to be turned into Eggs... unless the Derelict/or Eggs are NOT there at the time of this Prequel... but this would mean the Eggs are not there for Thousands of Years and THEN it means David is still the Creator.
I can come up with 3 different Plots/Movies and ONE does-revolve around David more... but all 3 will be similar as far as leading to Ending up on LV-426.... but they differ in HOW and WHAT happens...
I can Indulge you all if you like ;)
