Re: John Harrison was more interesting than (SPOILER)
I wouldn't have been against him being John Harrison or anothet Augment simply because I don't think they did a very good job distinguishing Cumberbatch as Khan.
There was nothing in the film that just screamed this needs to be Khan, besides Spocks scream.
Though I still love the film.
