I feel as if the way they went about Kenobi was all wrong. I think it would've been much better to explore such themes through his force training with Qui-Gon, not an adventure across the galaxy with physical confrontations, but a spiritual adventure across the force and his mind - with mental spiritual confrontations.
What we got had a good basis, but was executed poorly and very irresponsibly in my opinion, and overwrites/undermines several key aspects of canon.
