The degeneration of theatre

It is interesting that as a culture matures and grows "comfortable", that which is considered art degenerated into nonsense or depravity.  I would guess that this comes from that which people are seeking.  Most art comes from a culture that has had too much free time and too much money.  This mentality leads to boredom and thus the need to push the boundaries.  This leads to the need to shock or alarm. 
This sort of thing has been seen in ancient Rome, ancient Greece and Europe.  We are beginning to see it in the United States as well.  Unfortunately, like the proverbial frog in a kettle, we grow accustomed to it far too easy.  The Christian response is to step back, remove the emotional attachment and critique it for what it actually is, not for what we want it to be.
We need to learn to think like the church.
