Firstly, I would very much like to see the inclusion of more Sith sorcery in the Star Wars TV & film properties. In the Darth Bane book series, Darth Zannah was a uniquely powerful Sith due to her mastry of Sith sorcery - it made her an interesting foil to the brute strength of Bane - but this aspect of dark side powers is rarely illustrated in the Star Wars video media.
What I didn't care for:
- Child actors. The original trilogy didn't need them to captivate the imaginations of generations of children. The franchise truly doesn't need child actors for young viewers to relate to the story. It drags the quality of the end product down, bores and alienates adult viewers.
- The couching of the Jedi within a metaconstruct of abuse of power as a stand in for traditional power structures in modern society. "But", you argue, "modern civilization is complex, and it's important to reexamine institutional power dynamics and relitigate the legacy of our so-called heroes". Not here. Star Wars has always been a bit of a simplistic, unsubtle "good vs bad" story. Like so many recently-tacked-on addenda to classic IPs, it's clear the writers want us to reevaluate the goodness of the Jedi, and perhaps even sympathize with the complicated, misunderstood Sith. It's tiresome to be sermonized every time you try to consume escapist space fantasy. Sometimes you do just want a good guy you can root for, and a bad guy you can despise.
