Swearing

[Kreekakon]

Honestly I don't even see that as a problem, if I remember correctly in one part of Justine Basile (either him or Alois, I forget which) says "I'll kill you, you cunt!" as one of his idle lines, and to be honest I thought that was very effective.

I'd say it depends heavily on the situation it is used as well as the delivery of the line.

As another example, both "Batman Begins", and "Batman and Robin" had used puns. Mr. Freeze says a ice related joke, and it's silly as hell. However, when Scarecrow says "You need to lighten up" before lighting Batman on fire sounds badass. Why? It's all in the delivery, and situation the line is used. It's very important to keep certain dialogue from sounding campy.
