Every year a dozen horror movies are released with new IPs and they do well. People "liked" the Dune movies and that's an old IP that everyone already knew, right? Like every zoomer had already read Dune and watched the 80's movie, the 00's miniseries and knew it intimately? Of fucking course not.
All the girls and queers that watched Arcane were lifelong League fans?
People engage with new IPs all the fucking time, they just have to be IPs they find interesting.
Horror fans like monsters and creepypasta scripts, so they're happy.
Zoomer queers like gay little magic cartoons, so they get that and are happy.
What do dudebros like? Jason Statham makes a movie with an entirely new IP called "The Garbageman" and they're happy.
current cancerous trend of mystery box shows
I'm sorry, but earnestly the only trend chasing faggot is you. Calling a mystery show a specific meme-word that was invented 2 years ago doesn't mean mystery was invented 2 years ago.
