Huh? If memory serves, he doesn't swear any more in this movie than he does in the other Trek films. I mean, I think he says "you piss me off" in this movie (which he doesn't in any othe others), but that's pretty tame compared to his language in the (G-rated) Star Trek: The Motion Picture, which has "hell"s, "damn"s, and, I think, even a "goddamn" or two.I would have liked it more if McCoy didn't cuss as much as he did, that ruined it for me. And those little jokes that were slid in there that was not in Shatner's original script were not that funny either.
