This is just the evidence that a lightsaber is truly too devastating a weapon to place into a kid's show. In any sort of close-quarters fight where a Jedi Knight can use it to defend himself from blasters, it's certain death by UGLY dismemberment. The only saving grace is the cauterizing effect that stops it from being a literal bloodbath, but it's bad enough.
The zombie stormtrooper fight was ridiculous, using this video as a standard for how a lightsaber actually works. Should have been over in seconds, with no coming back unless they wanted to do the creeping, dismembered hand thing.
And I'm sorry, but even being stabbed straight through the brisket with star-hot plasma is going to kill you. It would flash-burn the organs, cook everything around it, and boil your bodily fluids. It's like surviving being hit with a stream of molten lava- you're done. Disney needs to get off this kick of nerfed lightsabers and blasters. Characters shouldn't survive multiple direct hits from those, either. Beskar armor or not.
