I am not sure how are you deciding on which supernatural powers that they can use and which powers they can't use. Telekinesis, Telepathy are ok but for example Regenerative healing factor is not? What is the basis of this 'difference between using a power over great distance and reversing fatal injuries in a split second' ? For example, in MCU, they invented time travel after some time. No one said MCU did some thing ''ridiculous'', its after all science fiction, same MCU that did many different supernatural events, and time travel was one of them. What you are saying ''ridiculous'' is just a basic supernatural power in MCU, or in DCEU or in any other science fiction platforms, that most supernatural character uses: regenerative healing factor. Not only 1 character has this power, multiple, nearly hundreds of characters has this in different science fiction platforms. And to say that another ''science fiction'' series such as Star Wars shouldn't have this power, otherwise is ridiculous is ''ridiculous''. Also note that, they didn't even use full regenerative healing factor on Maul or on Vader and on others. Those characters simply sustained themselves by still having their injuries. Maul didn't fully heal himself in that moment, he only had a very limited regenerative healing factor by using too much dark side of the Force that made him lose his mind in the end, he also used his dark side mastery to create those mechanic spider legs to sustain himself. It wasn't easy for him, it was extremely painful, and he paid a huge price like losing his mental health in exchange while surviving. They could simply give him the ability like full regenerative healing factor via dark side of the Force, and they could make his survival process much easier, but they didn't even do that.
