^ I guess the problem everyone noticed is that Prequel Anakin is just so different. Hayden Christensen’s physique and lightsaber swordplay is really not suggestive of Vader in any way. Hence, the emergence of this idea that the cybernetics fundamentally limited Vader’s movement - an idea that seems kind of absurd given the existence of things like General Grievous. Or forget Grievous - we have an 80 year old Count Dooku doing backflips. Even Yoda in ESB had very limited physical mobility, but was implied to be extraordinarily powerful.

But I guess Force powers in Star Wars constantly waver between the mental and physical, causing a lot of thematic dissonance. Yoda can lift small starships with his mind, but Jedi training also includes learning space fencing and space kung fu. You’d think being able to lift a multi-ton metal X-wing with your mind would imply mastery over physical forces that would enable you to kill anyone instantly, thus making martial arts or lightsabers mostly useless. Star Wars tries to justify the sword fighting with this implied rule that two Force users can’t necessarily just kill each other with the Force. But Vader as a villain/monster was designed for an environment where no other Force users exist, so he works better as a hulking monster than a master swordsman who does backflips.
