The plot is stupid. The execution of the plot is stupid and lazy.
They've made Kenobi into a stupid, weak, cowardly man. He's being led by a 10 year old girl, and he can't keep their cover story straight. He had one job at the conclusion of Ep3, protect Luke and train. Instead, he buried his lightsaber and forgot about the Force. He runs off from protecting Luke because a guy with an entire planet's resources behind him can't protect Leia, and can't find her, either. All I've seen so far is a pathetic attempt to retcon Leia into being more important than Luke. That may fit with Star Wars Disney, but it doesn't fit with what came before Disney decided to fuck up Star Wars.
More stupidity. Head Baddie lets an untrusted underling murder him because? The big showdown with Vader started with Kenobi ... running away from him in a gravel pit. Vader starts a fire to roast Kenobi, puts the fire out, and moments later is somehow foiled by the fire being re-ignited as a droid drags Kenobi away. I guess Vader is scared of fire if he doesn't initiate it? Vader can use the Force to throttle Kenobi, but can't do the same to a droid? Take a look at the moronic scene at that laser gate for evidence of a bad script. How about that great scene where the henchfolk can't seem to get their hands on a 10 year old? The writers and director really don't seem to care if anything makes sense.
Remember, this is General Obi-Wan Kenobi, not some bush league minor character. He was a powerful Jedi, central to huge battles and major decisions, accustomed to operating without support, and he beat Anakin when Big A was at the height of his Force powers. Kenobi knows what's at stake, and he knows the importance of his mission - yet, we're to believe he said, "Nah, fuck it!" and turned his back on everything. In the end, I expect Reva will be The One to Save them All, because Star Wars Disney wills it to happen.
Disney's gaslighting campaign against racism looks like nothing more than a diversion from the poor quality of what they're putting on the screen. This is the same Disney that pulled Finn from promotional material in China in deference to China's racist policies, and the same Disney that doesn't seem to recall that one of Star War's major characters was played by a black man, and pretty much everyone was happy with his performance.
