Why New Comedies Suck?

I have been watching some 60s and 70s comedy on Netflix. I specially like the comedies with the duo - Jack Lemmon and Walter Matthau (Odd Couple, The Front Page..). When these are compared with some of the recent racy movies uttering nothing but profanity in the name of 'Comedy' (Horrible Bosses, 30 minutes or less, Brides Maids etc... I didn't see these movies because I didn't think them worth my time), it is incredulous how people's perception of joy has changed.

God created so many things in life that give us joy. When God created Adam and Eve, He also gave them standards for 'legitimate pleasure' - the joy of food and work and creativity and even a sense of satire that pervades most of life. He also created the joy of loving sex within marriage. But the fallen man, having lost his communion with God has also lost his ability to enjoy the pleasures given by God in a legitimate way within the right boundaries.

Fallen man with his 'jaded' senses, takes sex outside of the boundary where its legitimate pleasure lies. He  makes of it a public spectacle using foul language on the movie screens causing disgusting reflexes among the audience which is taken to be good comedy. 'Dirty talking' has somehow morphed into enjoyable discourse. Unless we find our roots in subtle humor and brilliant wit of the kind that we had in Hollywood back in the days, I think human society would lose its ability to enjoy both the joy of good comedy and legitimate sex.
