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.
One of the few sequels that did credit to the original. Like the original Alien trilogy, it’s best if you consider them movies in the same universe but different genres. Like, Aliens (I) was a suspense; II was a sci-fi action; III was a horror thriller.
Maybe the Blade Runners weren’t so very different in genre, but yeah - good sequel, and in its way faithful to the original.
