The Mandalorian's great. I'm a little cautious about the whole raft of new shows announced as being set within the timeframe of the Mandalorian an hope that it's not setting up an MCU style connected universe that relies upon seeing all the shows to keep up. Hopefully it's more like the Netflix Series, which connected but focused on their own corner of the world.
I think I've put my finger on why it feels like such a great continuation of the original movies. The Mandalorian goes back to the same sources inspiration of the original trilogy - westerns and samurai films - and tells stories out of that inspiration, rather than using the original Star Wars films as your inspiration the way the new trilogy does. It also helps that Feloni is so involved with this series - he really is Lucas' true heir in terms of the Star Wars story. Feloni understands why the characters and their character moments are so important - find his description of why Duel of Fates is more than an epic lightsabre battles and actually forms a lynch pin of the prequels and the saga as a whole. Kathleen Kennedy may have been Lucas' pick to run the studio, but Feloni is truly the one to helm the story telling.
