To be absolutely honest? For me, the most disappointing aspect of the ST is that it isn’t about Luke rebuilding the Jedi Order. But for that to have worked, it would’ve had to been shot in the late '80s-early '90s, when Hamill, Fisher, Ford, etc. were still young enough to believably portray post-war/reconstruction era versions of their characters. The 2010s were just too late to execute a proper ST.
Most satisfying aspect? Daisy Ridley. She’s cute and a capable actress; I will watch her career with great interest.
