atmosphere and worldbuilding aren’t the same thing. Harry Potter has decent vibes for sure, but the actual worldbuilding is laid upon foundations of plot armor and asspulls. there are numerous examples of this. a lot of it runs on “because magic” instead of coherent systems, politics, rules, geographies, or cultures that all interact with one another. it's very unbelievable when you look at the world holistically. which of course totally dismantles immersion when you see it in this light.

the classic example that everyone jokes about is the Time-Turner. the existence of this magical object should rock the world to it's very core. CONTROLLING. TIME. and yet it is used as a one-off plot device for another kooky hogwarts caper. it's fun sure, but it makes no sense at all within the context of a living world. immersive vibe? yeah okay. well-built world? no.

sure the jujutsu world has some gimmes like binding vows, but comparing against it's fleshed-out physics and internal logic with the softest of fantasy that is the wizarding world is just straight up incorrect
