While nothing will vindicate Episodes I and II, Star Wars Episode III is now available in a nearly redeeming cut!
Ahsoka and Obi-Wan's stories are so much deeper and more engaging than Anakin Skywalker's. Much like the amazing Vader kicking ass scene in Rogue One, this cut of Sith puts some needed perspective on Vader, and makes Order 66 the gut-wrenching event it should have been.
Obi-Wan and Satine's story remains a favorite. Ahsoka is the best character in Star Wars.
Search for the full cut, it is not hard to find. You can also skip back and forth in Disney+, but the fan cut is really impressive.
