I watched a service for one of these mega churches once. It was about 80% their "rock band" singing songs, with people waving their hands in the air, and maybe 5% o the entire 2 our production was reading from the bible, but it wasn't even that. He took maybe a paragraph from I believe an acts chapter, then "explained it" in his bastardized way. And this wasn't a speaking in tongues church either.

It's sad that people are so lacking God in their life, they will seek out anything that appears to fill that void.
