I've been loath to the idea of a Khan re-hash ever since the rumor broke, preferring originality over re-treads and that hasn't changed. Khan had his fifteen minutes, leave him dead, IMO.
But I'm finding, if a retread is all they could come up with then the idea of it being Gary, Garth, Green, even Cochrane, (^

) who-ever, could make for an exciting Trek adventure in the Nuverse.
Despite my growing anticipation over this new Trek I will be severely disappointed if it turns out Khan. Just the thought of hearing his name said again in a brand new feature makes my skin crawl. I've endured a great many heartbreaks over decades of relationship with Star Trek but a Khan rehash here may be the final straw which turns me into a foaming Hater!
