I wrote myth in quotation marks because I didn't know what else to call it.
What I meant was that despite the generally poorly received films, Alien was still a kind of cinematic work of art and deserved better than a merger with another franchise. For me it was an admission of a lack of ideas and a new direction that was more towards computer games. Children suddenly liked it too.
There are also people who are of the opinion that Cameron's Aliens destroyed the "myth".
Then there are those for whom the prequels were the destruction of the myth. It's up to everyone how they see it.
Personally, I think A1-A3 is a good work of art, while I saw P1 and P2 as very good to good action films but never put them on the same level as the previous Alien films.
For me there was still a big difference in quality.
A lot changed with A4 and went in a more "embarrassing" direction.
With the Fusion Predator it had reached its sad low point for me.
Compare it to wine and cola.
I like both but wine is more noble.
So please don't misunderstand me, I don't want to offend any Predator fans since I'm one myself.
But up until that point, there was always a qualitative difference between the two for me.
I think A1 is a classic like Dracula or something similar.
P1 is a great action film but not a classic for me.
Even A2 isn't really a classic for me, it's a brilliant action film but it slips into a rather clichéd presentation.
Nevertheless, A2 is far more demanding than P1 for me, which is why I count it as part of the "Alien" work of art.
Of course it also depends on the zeitgeist of the publication.
The 80s were characterized by more action.
Maybe it's because the first films in a franchise are always considered the best.
So I can only give my opinion, whether it is correct or exaggerated,
I don't know.
