Just like with Blomkamp, you have to be careful despite all the promises and announcements from the "what could have been Alien3".
Wasn't there once a really stupid idea that the aliens would merge into one giant creature when they attacked Earth?
The comparison with ID4 is flawed.
Overrunning the Earth was certainly too costly for the Alien brand back then, because it is not a mainstream franchise.
Today this can certainly be done better simply because of the effect possibilities.
I stand by my opinion that an Alien film in the style of A Quiet Place would have worked great.
and it's good that we have Alien 3 as it is
