I know the type of churches you're referring to... they feel like motivational speaking with a religious slant. Very marketing focused to try to draw in a younger, more modern crowd. Large emphasis on music and video production. Much of what they teach is very shallow and the truths they deal in are the same as you might find from any motivational speaker. IMHO very little of substance to be found there.

I recommended checking out Pentacostal churches. I'm not Pentacostal but I've had friends who are and their churches tend to be much more traditional and wholesome. In my experience the people are all very friendly too.

Good luck to you. I hope you can find what you're looking for.
