A few issues that the Kenobi series may have upon the Original Trilogy films, events surrounding them, or other Star Wars releases. Along with some in-series issues too. With accompanying images, screenshots and memes.
I did originally post this in the Kenobi thread, but thought it useful to have its own thread, so it is easier to find, now the Kenobi series has finished. I’ll add any new updates, additions or revisions in here (but not in the original post in the Kenobi thread).
Not everyone will agree with some of the topics listed below, or the descriptions of these issues, and that is okay. Everyone’s mileage may vary. For some fans, the topics listed in here may not even be considered issues, inconsistencies or stretches.
I’m not a Star Wars fan who hates anything outside of the Original Trilogy, or auto-dislikes Disney Star Wars. For me, some of it has been great, some mediocre, and some of it underwhelming or poor. Many of us have been looking forward to this series for a long time; a much anticipated story, one that bridges the PT and OT, and Ewan McGregor returning to do justice to Alec Guinness’ iconic role. I did enjoy the series for the most part, but like a number of others, there were some noticeable issues.

Once again Obi-Wan was in a situation where he has Vader beaten and at his mercy, he can end the suffering of many others to come… and yet Kenobi just lets him walk away.
Knowing what has occurred in the galaxy since he left Anakin defeated on Mustafar last time, knowing what Vader has done to innocent people in the years since (not just the men, but the women and children too), and something he has seen for himself first hand on Maputo, when Vader killed the civilians in the street to goad Obi-Wan into action. That Vader would go on to murder, destroy, oppress, over and over again, and that no-one else has been, or is likely to, be able to stop him.
This really is a poor decision, and writing, to have Kenobi 10 years on in a situation where he has Vader, a “master of evil”, beaten again, and yet instead simply walks away, for a second time.
Instead, years later in ROTJ, Obi-Wan will instead persuade Luke to go and kill Vader, something he did not do himself on two prior occasions now, at the cost of countless lives. When Luke refuses this in ROTJ and says “I can’t kill my own father”, Obi-Wan responds with “then the Emperor has already won”.
On the scene: it was basically a homage, or repeat, to what had previously been done years ago in the Rebels animated series:-

There are also many “similarities”, homages, “they rhyme”, or rip-offs, with Jedi: Fallen Order video game and episode 4, here:-

Kenobi doesn’t want to kill him, and both times he refuses to kill Vader. He’s his brother(metaphorically) and not only that, he has two kids he doesn’t know about. If he were to tell them I killed your father, it would be devastating to them. He couldn’t do it, both times. The twins would hate the Jedi if Kenobi killed Darth Vader. Obi-wan showed Luke that Darth Vader is evil by sacrificing himself.
That’s why Yoda knows it can only be one of the twins, preferably Luke. He must face his father one on one.
