Watched the episode where Rosso becomes Bloodwork. His moment of transformation: He realizes that the blood supply he’s using lacks epinephrine, so he needs to get it from scared people, which means he has to kill them, and he’s willing to do that to stay alive.
COME ON.
He’s a doctor. He can buy epinephrine by the gallon if he wants, cheaply. (Most of the cost of epinephrine auto-injectors is the device. And greed.)
Story done.
My suspension of disbelief works a lot better with wild and crazy tech/magic/”science” like dark matter, super-speed, multiverse teleportation and so on than with something that they try to make “realistic” but completely miss.
