Created Star Wars =/= grounds for unconditional praise. I liked them all before he decided they were flawed and needed improvement, now he's trying to rewrite history and say that what everyone saw for the first 30 years of its existence is wrong. And that thar is f'ed up.
Like Ady said (or not, I might've made some deliberate creative changes), this site exists pretty much to shame Lucas' crowd into an honest effort.
