My only hesitation so far is the cinematography. Something about it - at least in the two admittedly short trailers - just looks flat and dull and a little too "small"/TV-ish. It doesn't *feel* cinematic, like a big, sweeping, desert-set, planet-hoping story should. I don't know, I just thought this was going to look more epic and grand and not saturated, digital, and somewhat hand-held.
That, and from a million miles away I can already see the Reva character turning "good" in the end, or at least finally helping Obi-Wan out in some way.
As for everything else - the story/concept itself - I'm all in, and obviously can't wait to see where it all goes. They've been developing this thing for so long, and seem to have put in the work on the script stage, that I'm not too worried about the narrative, characterization, etc.
