I think for me it’s alien: covenant. I was really interested in the ideas explored in prometheus and covenant just expanded on them. I don’t get much into the details of why it is or isn’t a good movie.
Luckily, though, HBO ran raised by wolves which really delved into ideals about AI and planet seeding etc. So that itch got way scratched even if the run was cut short.
There’s only one sequel with a 2nd supposedly in the works.
This shows how much I didn’t enjoy the second one - I couldn’t even remember if there was one or two sequels, but I do remember there was supposedly another instalment in the works.
