For some reason sequels are extra eager to walk into this trap, thinking the energy field and the virus are what made the original so compelling, so this time let’s have the story revolve around 3 energy fields and 8 viruses.
Side note, but this perfectly describes why I liked the first John Wick, where the world of the assassins is an interesting background element, and hated the sequels which are exclusively about the assassins and their weird rules and traditions
