That always bothers me in zombie movies - they rarely break windows. Drunk people accidentally break windows all the time, zombies (shown with the strength to tear people apart and no concern about injuring themselves) would go right through windows without even noticing. But zombie movies come from a tradition of doing really cheap movies, often in real-world locations, where breaking windows wasn’t an option.
Zombies are now culturally on par with monsters from folklore like vampires or werewolves, but unlike all of them, there’s no traditional lore that informed how they appear in movies; instead, zombie lore was created from what we saw being depicted on movie screens. So we’ve got this fascinating collection of zombie conventions that came purely out of the films being cheap. (And another set of conventions that came out of them being cheap, poorly thought through movies that didn’t sweat the details because they were intended to be metaphors anyways.)
That also struck me. Some (apparently unintentional) humor there.
