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.
Super Mario Bros (1993)
It was objectively a trainwreck but it was awesome when you were 8 and It brought video games to the big screen for the first time. I will always love it.
