"Genre blindness" re: zombies completely kills immersion for me

I really hope this trope gets retired at some point. The fact nobody's ever heard of a zombie and that zombie media apparently doesn't exist in-universe just goes out of its way to remind you you're watching a movie. It maybe worked in the 60s and 70s but not anymore.

"But then everybody would know what to do and survive" do you really think everybody would act rationally and survive if a zombie outbreak did actually happen irl? Come on, lmao. If anything people would be trying to participate in the "spectacle" adding to more chaos and fatalities. So many people would be trying to play action hero
