the original turtle movie managed it. There was alot of cursing in that movie actually from what I remember. Alot of parents complained especially with the turtles using their weapons on people (I know stupid isnt it) So when the second movie came around (still a good movie in my opinion as well), you saw the turtles use inanimate objects instead of the weapons on people and the language was toned down.
So if they keep the tone like the 1990 turtle movie then I am happy.
