There were nameless Extras in Rogue One, with only a few seconds of screentime (such as the Rebel who desperately tried to get the disk through the door as Vader pursued) that I found much more compelling than the combined casts of characters in the Prequel and Abrams Trilogies.
A very high caliber of casting, acting and screenplay was the rule rather than the exception in Rogue One (I find opposite to be true for the Prequels or Abrams/Johnson trilogy, with a great deal of script-writing and acting that feels amateurish), so even without the hours of screentime or backstories, characters like Jynn Urso and Cassian had much more gravitas/weight/audience-connection than any of the Pre/New Saga characters (who?). In Rogue One, emoting or simple interchanges didn't sound cheesy or forced, as I had become accustomed to - I almost forgot that was a possibility in a Star Wars movie... that free, natural, professional acting of a 1980s Han Solo or Obi Wan.
And that's just the acting/characters. R1 has stellar production design (perfectly recalling AND expanding the Original Trilogy vision in everything from ships to hairstyles to costumes) and visual affects (the best looking Star Wars ever made, particularly in terms of battles - CGI looked like models) and story (galaxy-shaping, momentous events unfolding; believably-balanced battles; flawed heroes; life & death choices/sacrifices).
Rogue One is the first and only Star Wars movie that I have seen as an adult that stirred/electrified/gave me goosebumps throughout - one of the best movie theater experiences of my life (no expectations or spoilers helped). It made me care about Star Wars again... which lead me to this thread's subject.
While nothing in the Disney era has - for me - approached "Rogue One" in terms of quality, I put Mandalorian around "Solo" level, maybe slightly above. This is a good thing. So far, the Jawa battle is the easy highlight.
