How is it stagnant? They've gone off in different directions with Engineers and androids and black goo.
It might not be everyone's cup of tea, but they're not simply repeating the same thing over and over.
Same film beats, three different times, from Ridley.
You can probably lay that at Cameron's door, expectations for what makes an Alien film apparently comes from rehashing ALIEN, and Aliens does it beat for beat, but Scott does it whilst opening up a broader scope.
..now that Covenant was released and the majority of the public didn’t care for it....
Box office receipts are heading downwards generally - Alien isn't Wonder Woman or Star Wars, so it's a broad statement to say the majority of the public didn't care for it. Certain territories cared for it more than others.
It’s somehow Cameron’s fault Scott keeps retreading beats from his own film? Okay, then.
As for a broader scope? Yes, Space Colonization, Colonial Marine Corps. and introducing the Queen Alien are totally NOT broadening the scope.
They might have the odd same beat here and there - it's an Alien film so each film is going to offer up certain expected aspects - but again they're not telling the same story over and over. It doesn't matter that the Engineers and goo are gone - the point is they were introduced as something new.
It’s the same beats and different versions of the same story. Also, it most definitely matters if the engineers and goo are gone. What’s the point of introducing new concepts? Only to do away with them as if they never mattered in your sequel? That’s bad storytelling anyway you spin it.
What is stagnant though is this fanbase since the release of Covenant. Every discussion devolves into 'Covenant sucks/ no it doesn't'. Or 'Ridley is an old fool who doesn't know what he's doing/ more Ridley prequels plz'. Or 'Blomkamps movie would rule/ Blomkamps is a desperate hack who wants to make colonial marine movies for idiots'. It's all a bit disappointing.
I’m sorry, but I haven’t seen you do anything to change the narrative. In fact, you do your part in stirring the pot. This is where the fan base has been since 1992. I don’t think Covenant changed much in the way we all disagree. It just changed the subject.
