I mean really, maybe “getting stuck in time loops” is actually a problem of the modern era, so some nice people decided to create these media as an instruction manual in case we do get stuck in time loops… or sent back through time, or parallel timelines, alt-universes, or some other space-time shenanigans, etc…
I still love the part of Haruhi Suzumiya where everyone’s stuck in a time loop for several episodes. Like each episode is the exact same with maybe a couple shots being at different angles, but one line changes to tell you how many loops they’ve been on.
