My hope is now that JJ and co. have Khan out of their systems, they'll do something more original on the next outing. I really want to see more of the Klingons in this universe. I think they were the best part of Into Darkness
; they looked absolutely amazing.
My hope is that's the focus in the next movie. Just don't retread anything from The Search for Spock
I will say this, though. I know it was dealt with on Enterprise
, but I really loved the whole idea of the Klingons experimenting with genetic engineering after the three part Augment arc.
