It's all in what you say.

I happened to catch a movie called "Mermaids Chair" the other evening. Good movie, I thought, but one I can't recall hearing anything about. The movie was finely acted, well photographed and the script was done by someone who knew how to use the language to tell a story. As proof there was not one bit of vulgarity throughout the entire movie. How about that!
Now, I'll tell you up front I've used some words I wish I hadn't over the years; I'm not proud of it but that's what happened. These days I find the English language capable of providing me with enough material to verbally slam anybody I choose and still be able to use the sentence on television if I need to.
It's hard to go to a movie and not notice the foul language used almost always without justification. See, I allow for it in a movie or a book if it fits the character and the location but when the stuff is thrown in almost at random I see it as coming from a lazy, untalented writer who isn't capable of doing better. This seemed not to be a problem for the writer of the movie I watched.
I like good movies and good books; I like them more if their writers can get along without using a four letter word for a crutch.
