I mean - IGNORE ME!!! Figured I could post some thoughts here without polluting the greater wiki.
Had a real life Watamote moment - last one was finding 'Twice-Cooked Pork' on a restaurant menu (it's delicious.) This time I went to a beach infested with Stingrays. And because I live in America and not Japan, I did not learn this by seeing a sign; I learned by getting stung. If they do a live-action Watamote Netflix movie set in the US (Death Note style,) that part of the story will end with everyone burying their feet in hot sand for almost three hours in a vain effort to mask the searing pain.
Now that walking is uncomfortable and I'm lying in bed, I'm thinking about re-reading/watching Welcome to the NHK. I admit I sort of avoid Nico Tanigawa's other works on purpose, to not overload or dilute the impact Watamote has; I'll read them someday, but not now. If you haven't seen Welcome to the NHK, it is *very* thematically/tonally close to Watamote, but quite different angle and a more plot-driven/dramatic (rather than slice-of-life) approach. It's nowhere near as thoughtfully crafted as Watamote IMO, but it has its intelligent points and it hits them. Curious what anyone thinks of it if they're familiar; it's been over ten years since I've watched/read it.
