I won't be making Rebels part of the fabric of the blog often but I am compelled to say that episode 1 of Rebels season 2, The Siege of Lothal, was the most exciting Star Wars-anything I have seen in a long time. They took serious notes from movie Episodes 4-6 in terms of visual styles and aesthetics and I appreciated the hell out of it.
Being a McQuarrie fan since childhood, I see so much of his handiwork embodied in Rebels, from Lothal itself to the profile of Vader's mask and while I have enjoyed how Disney deployed his conceptualization from the beginning, something really congealed in this episode, really pulled together his signature influence and the classic Star Wars look from A New Hope onwards. Visually, it was more Star Wars than I though a cartoon could get, in due part to the "classic" look of everything on screen (no offense Clone Wars) but also the spotlight on Vader and how the universe "felt right." GOOD lightsaber fights, A-Wings, CR90's lumbering around, Imperial scapegoats... and Vader. Such Vader. Wow.
Season one was a bit childish and weak (even my 11 year old says so) but it is desirably dark now and feels so Star Warsy it has me scrambling to play Imperial Assault and X Wing (well played Disney).
If you haven't watched the series until now then you could simply jump into this episode and maybe feel thrills you forgot you once had, even without all of the back story there. Those with the Lucas-trope gene will know how to fill gaps in motives but if you had a choice I would say watch Season 1 first.
You may be surprised at how into it you get. Either way, enjoy!
