I am already finding it hard to watch in mid 20s and only watch stuff I watched in my teens due to nostalgia that I have to turn off midway through, I despise the optimism, paperthin characterizations, teenage novel level writing and most of all the youth and school settings (that have the double whammy of appealing to old and young, very cheap trope to broaden an audience) that only really try to explore things from a japanese, probably low inhibition and autistic normgroids perspective, throw in a cuppa just world fallacies and platitudes about work ethic and collectivism and you're really in glorious nippon steel mode.
Watch some Kurosawa or kobayashi movies instead if you want a distinct japanese flavor but with actual engaging themes, should appeal more to us westerners especially the ones that are based on shakespeare.
