Big churches are oddities. I guess they provide what they provide. There's music and then preaching. I think many of them have set up small group programs to compensate for the fact that going to one of these churches is like going to a concert. It was like when I was in college and had giant lecture classes, I didn't make any friends in those classes. People mostly sat in random spots every time, so you weren't next to anyone long enough to make friends with them. These days I meet with members of an obscure group at a house over dinner. I much prefer this to most church services. The only really good church services are often guest preachers at small churches. Outside of that it's usually just stupid music, basic preaching, and goodbye.
