The Uhura book scene and not being able to speak Klingon fluently was Stephen Meyer's idea. Nichelle Nichols brought up it didn't make sense for the Klingons to be the Feds number 1 enemy and she the communications officer not be able communicate with them. Meyers said the scene was funnier the way he shot it so he left it in there.
I don't mind the Spock forced mind meld scene since he's doing it on another Vulcan who is most likely trained in resisting mental attacks. Although Meyers had said recently he regrets shooting it the way he did. With water boarding and torture used by the US government on it's prisoners in recent years
