I really enjoyed this movie. It's not without its faults, of course (I still have a hard time swallowing Kirk as captain with so little experience). However, the wonderful performance by Cumberbatch allows me to shrug my shoulders a lot. I still think the story would have been just as good with Harrison as another augment, rather than Khan. I think Cumberbatch as a villain was IMO much better than Montalban ever was, both in terms of writing and acting, but then I've never liked TWoK much. The role reversals (Spock's "Khaaaaan!" and Kirk's "dying") did get a smile from me, as intended.
