The Slacktivist has this to say about some Christian entertainment:

The evangelical subculture is awash with bad art and dismal entertainments. From the Left Behind books to the vast majority of “contemporary Christian music” (which is none of the above) evangelicals are eagerly buying up awful dreck, the consumption of which makes them worse people, worse neighbors, worse citizens and fundamentally worse Christians. This is theologically awful, politically vapid, aesthetically blasphemous stuff.

I think this is the main reason why I flinch a little whenever I pass a “Christian store,” of which there are many where I live.
