I think it's one of those deals where the people buying the movie aren't doing it for themselves. Whenever I've seen anyone put one of these movies on, it's always a situation like grandma feels obligated to show a movie, and thinks a comedy isn't likely to offend or bore anyone, and that's what's available so that's what she plays. Nobody complains because that would be rude and it's not so bad you can't just ignore it.
