SC 38 Reimagined is prequelized junk. Vader needlessly calling his lightsaber to his hand telekinetically is proof enough of that.
Perhaps the original duel is a tad too clunky and claustrophobic. Perhaps it could do with a facelift. But this overwrought masturbatory exercise isn’t the way towards doing that.
What’s “masturbatory” about showing Vader actually use the Force? Why shouldn’t space wizards with cool space wizard powers be shown using their cool space wizard powers?
Because subtlely trumps sound and fury signifying nothing.
It signifies Vader’s high level of power and skill in Force, setting him up to be an incredibly daunting challenge for Luke to face in the future.
