The last episode was ridiculous.
The force powers were over the top. How can Obi Wan go from a mumbling weak coward to defeating Darth Vader
The whole series was poorly written and made for kids. Unfortunately my star wars nostalgia is what keeps me watching
There are a couple logical ways to explain it.
Kenobi was out of practice, but not out of shape. Between the work and Tatooine harsh environment, he wasn't
. Also, the whatever amount of time running for hos life and fighting snapped him out of his lull. If you believe the goofy midichlorian shyt (fukk you, Lucas), the ability never leaves you.
Also, Anakin wasn't too far removed from being a padawan, just an incredibly talented one. He also could not have 100% recovered from the injuries from Episode 3. They aren't super clear how mush time has passed. As shown, Kenobi knew all his tendencies and weaknesses.
I liked the show overall. I don't like prequels since you know the results to a degree, but this had some good action, and the dynamic between Anakin/Vader and Kenobi was interesting.
