IMO Children of the Corn (1984) should be remade because the concept is great but the movie itself is terrible. I assumed it was some sort of horror classic because it's so well-known and has an iconic poster, but then I actually watched it and, yeesh. feels like a bad TV movie
what are some other movies that deserve a remake because they have a good concept but bad execution?
Warm-ish take: Idiocracy
It would be a fairly big change ideologically, but I think if you removed the eugenics and instead made the backstory about the privatisation of education and the need for politically illiterate workers, which gets resolved with faith in humanity and solidarity at the end. I think the corporate critique/regulatory capture lands really well, and would fit in with the premise and themes, as a comedy. It wouldn't actually change a huge amount of the overarching plot or even scenes and would be a lot more sympathetic to the future people, more poking fun at bureaucracy that delivers nothing and obsequious managers.
