We have a character that looks nothing like Khan, sounds nothing like Khan, and has a plot which could have been filled by anybody. I wasn't offended , I just didn't see the point of just throwing Khan away like that.
No,we have an actor who does't look or sound like Ricardo Montalban.
Really, because the movie I saw needed a guy who was a highly intelligent, super strong product of "selective breeding". Khan would seem to fit that bill.
