I know it’s still fashionable to hate on George, but look at the expanded universe, fan fiction, and TFA itself. Others attempts at expanding the story are overwhelmingly not good, and lack the substance of George’s direction. It is his story and as such only he can tell it.
I’ll take 50% of the EU, 10% of fanfiction, and 30% of TFA over 100% of Lucas’ direction anyday.
