Nah, the "Mega Church" movement in America is essentially the branding and corporatization of organized religion. The focus is on huge congregations (one in Texas meets in a football stadium...and fills it up), and positive "feel good about yourselves" preaching.
The facilities are typically far more like theaters than churches. Gone are the pews, replaced by movie theater-style seats. Gone is the altar, replaced by a stage complete with curtains and spotlights. Gone are the hyms and the liturgy, replaced by dramatic scenes acted out under theater lights by amateur actors and pop bands jamming away at contemporary praise songs. (Which, I am convinced, are pretty much all written by Satan. They make my ears bleed. If you really want to hear good Christian music, swing by a black Southern Baptist church. The sermon might scare the crap outta ya, but the music is first rate!)
These Mega Churches provide all kinds of services like day care, counselling (the financial kind especially), exercise rooms, and all the rest, designed to make the church the absolute center of a person's spiritual, physical, and social life.
Sin and redemption are rarely addressed in the preaching of these churches because that's a "downer" and might drive people away from the church to another one that tells them how great they are. They tend t focus on simple, cut-and-dried issues like drug use, family responsibilities, citizenship, sexual responsibility, kindness, generosity, etc. The doctrine tends to be as generically Christian as possible.
All this is centered around the goal of the church growing as large as possible as fast as possible. It's a business more than a church, and it's run that way, attracting the choosy "consumer" with facilities, advantages, a slick come-on, and snappy patter.
It's all kind of sad, really. Essentially mass-market, fast-food religion.
