Agreed 100% with the OP. John Harrison was a good villain, and far superior in both writing and acting to that annoying cunt Nero in the last film. Making him Khan just rid him of importance, and means he'll be stuck as the "lesser Khan" in many fans' eyes, rather than the great original villain he should've been. I still kinda liked CumberKhan though, as he was painted as pretty sympathetic in a way that worked. Whereas Nero was just a total gorm that was poorly acted.
