This series is completely unnecessary and did not have an actual story to tell
So I mean... what was the point of this story... again?
Leia is kidnapped, but we know she is not killed and not in danger at all.
Obi-Wan is devastated about what went down 10 years earlier, receives a call to action and saves her.
And... that's it. That's the story they are telling. It's weak, pathetically structured and completely inconsequential. And they couldn't even be consistent with the other films!
I mean are we seriously to believe Obi-Wan and Vader ran into each other twice between ROTS and ANH? None of the encounters were particularly interesting, and both instances did nothing more than to cheapen the characters and the mythos around them. I mean Vader's line in ANH about "This is a presence I haven't felt since..." is a beautiful line, implying history between Obi and Darth, and even the prequels cheapened it by outright showing us what went down... but it lands much better if we imagine the 20 year gap between their duel in ROTS, and not their duel on... generic dark rocky planet #344.
Furthermore - are we seriously to believe that Obi-Wan had Anakin completely defeated not once but twice... and he did not decide to end it? I mean it was bad enough in ROTS and completely out of character for Obi-Wan to let Anakin die a horrible death burning to death, laying on the ground mutilated... But now, he knows what Vader is doing to the universe. It's his duty to stop him. He is clearly beyond saving - and he lets him go again? I mean I understand how hard it would be for him to kill him, but come on, there is clearly no other solution here - but he just leaves. WHAT?
Also - Vader spells out the line "I killed Anakin" - to server as the blatant source for him saying the same thing to Luke ("... from a certain point of view"). This is too on the nose and completely unnecessary. This was understandable even without the prequels back in 1983! Why are you insulting the intelligence of the audience???
Also - Obi-Wan is learning Vader's identity from Reva??? Freaking WHAT??? He already knew Anakin's Darth name was Vader! He cannot be that stupid not putting two and two together! Yoda warns Obi in ROTS that he is afraid Darth Vader has consumed Obi's padawan! HE KNOWS ALREADY - WHY IS THIS TREATED AS A HUGE REVELATION???
Also - How does Reva know? Maaaaybe she is sensing Vader's presence and it is the same as Anakin's force presence...? That is one explanation, but it's a bit of a stretch.
And lastly (I could go on and on, but enough for now) - Are we seriously to sympathize with Reva, a character who gets wronged by the Empire (Vader) and... joins them? Hurting innocents? Killing and hunting Jedi? All under the pretense of "she is undercover"? She might be undercover, but still decided to kill those people! What kind of f_cked up morale is this?
I really wanted to like this, but ridiculous things kept on piling up, and the overall series did nothing more than to actively hurt the SW-mythos, so... I'm erasing this from my headcanon altogether.
MacGregor is a really good actor, but was given really weak material... for shame.
