Pretty much this. Plus the fact that he is a quadruple amputee who lives in an iron lung probably has something to do with his lack of flourish as well. There isn't much space to move around in that hallway either.Gethsemani said:His fighting style, likewise, mirrors this by being subdued yet efficient. It shows that Vader wastes no energy, because the half dozen people in front of him pose no risk to him, he will kill them and he will do so without even trying very hard.
I am surprised to see the OP applauding the choreography in the prequel trilogy. Phantom Menace had a pretty decent fight with Maul, but after that it got completely ridiculous with the weightlessness of the lightsabers and all the acrobatics. I've seen pretty universal criticism of the saber duels but that may just be my experience.
