There’s a lot going on–maybe even a bit too much because from a narrative standpoint I have no idea why things are happening beyond the obvious. In some instances that’s not a bad thing.
In this case? No so much.
Though at least Orci and Kurtzman aren’t writing because the moment when ‘Bones’ McCoy (Karl Urban) decided to give a Tribble a transfusion of Khan’s blood–never mind the whole Khan reveal in the first place–I accepted that with Star Trek: Into Darkness the franchise had official jumped the shark (though their penchant for ‘magic blood’ as a plot device was the Fourth Horseman of the Apocalypse as far as movie Armageddon goes).
