Search the web for "TV Guardian." Its a device that filters out the garbage talk.
1) Christian do not want to watch sex on TV (pronography) so that should cancel out a whole lot of movies rigtht there.
2) Curse free silences the movie and replaces the dialgue with a closed captioned at the bottom of the screen. So if you watch a foul mouthed movie, it will be a "silent movie" and that is not entertaining, so you would cut down on those as well.
3) Throwing out the TV is a good thing if you must.
I don't watch anything I can't filter. Even when we watch a series, like LOST, we will buy the DVD as it comes out to control what we see.
Even when we watched the World Series last year (or it may have been the year before) there was a very lwed commercial on that we were appauled at. And little children are watching baseball with thier parents thinking its going to be a family time!
