I didn't like the farm animals line either. It was one of the few non-family-friendly moments in the film for my preteens.
This is exactly why i didn't like the line and would have preferred that they not used it.
Meh. Like I said above, the bar fight upset my girls more than any lines said in the movie. That was a pretty intense fight scene for Trek. Kinda shocked me, too.



And when you have fights, there is blood. Duh. What else do you want? Completely unrealistic fight scenes?
