I loved the episode, I can see why fans are complaining, but it’s the little moments that count the most to me. Whenever Kenobi is talking to Leia about something from the past, it just breaks my heart. Both of their performances are very good.
As far as Vader, this isn’t Vader from A New Hope. He too, is on a journey, just as Kenobi is. It’s like looking at something that isn’t finished yet and saying that sucks, it’s horrible.
There is another duel and I’m sure Kenobi will show Vader why he’s still the master, angering Vader even more. This loss in the next duel will make Vader upgrade his armor and helmet even further. Like I said, he looks cheap and different because he never had to go up against a strong Jedi Master, such as Kenobi in the last 10 years. His armor is weaker due to no contest against the weak Jedi he ran across.
Kenobi is only fighting at like 50% in this episode, because the force is slowly going back to Kenobi. In his final duel with Vader he will be at 100%
I just have a strong feeling that Kenobi wipes Leia’s memory because she finds out something. Maybe she learns her father is the man in that horrible black mask. It might be too traumatic for her, so he removes those memories of them together and her learning the truth.
Remember in Return of the Jedi, when Leia says to Luke, “I know, somehow I’ve always known.” She knew Luke was her brother and Vader was her father, but Kenobi removes it from her memory. When Luke reveals to her they are brother and sister, some of those memories return to her.
I also think he tells young Leia that if she ever needs him again, she can find him in the Jundland Wastes on Tatooine. Maybe R2-D2 is there when he says it, that way he knows exactly where to go on that big planet.
