Oh he wasn’t good (less terrible) for signing the Magna Carta, which wasn’t even that important at the time, but more because his competition is worse. And yeah, no one named after him, but that’s only relative to other monarchs - as in, he was bad to the royals. Failing at being a king can make you a good king, depending on how you’re judging it. Nobles thought he was a prick, but they were, so it’s like 6 of one. For example, he reformed the legal system which took power away from barons (which obviously favoured him), which was very popular with lower classes, as they could since seek justice against their barons (who were previously the ones overseeing those cases).

My opening line was mainly a joke, I don’t like any monarchs, but the idea he was particularly bad is… contentious
