I think Obi-Wan is on a similar journey in this series, but he will end up finding some sort of inner peace and resolve in order to make a better future by training Luke and Leia.
I think everything will get tied up in a bow when he gets his "training" from Qui-Gon (which they made sure to put in the prequel supercut before the first part) and he switches from using the Force like the Republic Jedi did, to following the Will of the Living Force as Qui-Gon did. If that happens in the next couple episodes, he could be super-charged for his next battle with Vader, and leave his apprentice feeling like he needs to "learn" something new.
Or if they don't, it goes to explaining why once we catch back up with Ben 10 years later, he is as chill as he is--living with 2 lightsabers right under the roof of his publicly-known home, and ready to charter a ship and get back into the fight at the drop of a hat. It will be quite the change in attitude once he starts using the Living Force as his guide.
I have a ton to say about Vader and his actions from part 3 as well, but I want to see what he does next to clarify if he was supposed to have been stymied when Ben got away or if that was all intentional.
For some of the production clunky I am really enjoying the character beats in this so far!
