Disney is unable to produce anything which is not a blatant OT rip off. That being said, it’s possible to enjoy the show, and this brillant finale. Season 1 was ANH reboot, season 2 is ESB reboot. Not very convinced by the simili Zimmer ending music (not very Star Wars) but the emotion (Vader, Ahsoka, Maul) sealed this finale as the best this series has offered yet. As a bonus, Sarah Michelle Gellar’s Seventh Sister laugh is going to be historic.
By the way, those who are still believing that Disney will eventually declare the PT as non-canon and will hence produce new Ep I-II-III should really forget their hopes. PT and OT have never been so tied than they are under Disney’s rule. For the best I may add.
