I'm now really enjoying the show, I rewatched episodes 1-3 last weekend and even my original issue with doing Vader so early isn't a problem for me now. Just finished episode 4 and enjoyed that as well (basically an episode full of stormies and you can inject that into me anytime)
I get the annoyance with some of the writing but to me that just makes the show fit so well with the prequel trilogy because they weren't great films at the time but they've aged in such a way that they're really enjoyable now (well not Phantom Menace)
My main gripe with this show is Leia and how her arc just doesn't fit with A New Hope, why would her hologram message to Obi Wan say 'General Kenobi you served my father in the Clone Wars' rather than 'Hey Obi-Wan, remember me and how you saved me when I was an annoying brat?' makes no sense that. I'd of done away with Leia completely in this show and just have Obi-Wan be rescuing some random youngling we've never heard of before
Really looking forward to the final 2 episodes with hopefully more troopers, more Lightsabers and more Vader
