So Lucas wanted to do his own version of the EU. Sounds like with some edits like Luke neither being married or having any children. No wonder Disney threw those treatments in the trash. None of these are new or original stories or ideas he was just cribbing EU characters and plots. Maybe even worse than Disney in a way, more lazy at least for the most part Disney didn’t use the EU as a template.
Darth Maul being the main villain is a joke.
This isn’t what we waited 35 years to see. We waited for the continuation of the OT characters and their story where it left off, as original stories. Not some weird amalgamation of Filoni Clone Wars and EU.
Sorry for the late reply, but I think you have this backwards. It isn’t George cribbing on the EU and Filoni, it was his guidance to the EU authors and his instructions to Filoni that would have created a unified tale. Filoni resurrected Maul at Lucas’s instruction.
