George Lucas:
Set up LucasFilm, Industrial Light and Magic (has made visual effects for over 300 films), Skywalker Sound (about 30 films a year, have won 18 Academy Awards) and Pixar, all of which have done massively more than just Star Wars, has made a huge number of films, has used his fortune (including a lot of the Disney sale) in a wide range of philanthropic endeavours. The Rebels series that gets talked about a lot on this forum and despite being a kids show is fairly popular? That's an evolution of Clone Wars which George Lucas was directly behind. Also behind LucasArts which, while it may have got to **** in its last few years due to severe mismanagement issues, produced a huge and wide ranging amount of material since it opened in 1982. Monkey Island springs to mind. Oh, and he's why credits are at the end of films.
This is barely scratching the surface.
But no, he made three films that weren't as critically acclaimed as three other films he made (they were still massive box office successes and the people who claim to loathe them "because it's cool" are not the majority), and thus he deserves to be hounded and mocked by a massive internet circlejerk for the rest of his days.
He also really really wanted Indiana Jones to be a Pedophile
