@Arkandel I think this is one interesting byproduct of living in this crazy cool era where a lot of our nerdy stuff is popular. My mom sent me a message saying she's excited for Avengers: Endgame and asked if this makes her a nerd. I told her: "Nope, just that you have good taste".
I think a lot of people didn't give this stuff the time of day because there was a stigma surrounding the concept of the nerd. Revenge of the Nerds was a thing. The image of the Louis Skolnick pocket protector nerd or the neckbeard spending all day at a comic book shop was pretty prevalent. Cut 20+ years later and people are excited about the new Dune movies, my mom knows who BANE is, and fangirls over Bucky Barnes. Right, because it was good shit if you got out of your weird self-conscious box to give it a chance.
ETA: Oh, and her Winter Soldier thirst is a thing. Jesus Christ. Thirrrrst.
