I was not expecting a direct confrontation between Obi-Wan and Vader. I was also not expecting Obi-Wan to be nerfed so completely.
He's been shown to be doing fairly demanding physical work, long shifts at the sandworm processing tent, riding his space camel, etc. And we saw him being decisively fast in the Star Wars cantina fight in A New Hope, and in Star Wars Rebels.
Obi-Wan Kenobi should not be standing there flatfooted as if to say "Jeepers, he's using the FORCE!"
Are they making Obi-Wan lame to try and make Vader look tough in comparison?
It is genuinely odd to see Obi-Wan Kenobi drawing his lightsaber, and it coming across as an admission of weakness.
And speaking of Vader, I know they're trying to recreate the Vader we saw in Rogue One, but I still don't like the way he moves and fights. He's slow and lumbering, as if his mechanical limbs don't work all that well. But there are plenty of Star Wars characters with cybernetic arms and legs who are every bit as agile as flesh and blood. Also, he doesn't move or fight anything like he does in the prequels.
