These are good formats to go for someone that has never heard about Jesus, or are afraid of going to a real church and just need to listen to some good Christian music along with a little rant/ramble on stage, but that's about it.
These are typical churches that have sprung up all over the place. Sadly too many people use them as a replacement for a real church. You may end up just watching a video screen rather then a real person preaching. The messages are typically lacking in any substance, and very little of the bible get's read, some of the tangents discussed have nothing to do with anything at all.
The sad truth to it all these days though, too many real churches limit their operations to only short bits on the weekends. Filling in the gaps, such as with LH during the week, it's entirely a case of the fact, there is nothing better going on, so where there should be something in place, people are stuck with a counterfeit.
It's a classic case of big business in play here, and clearly they are leading the pack in that area. There is real money to be had for anybody that want's to create their own, and many clone operations just like theirs out there.
So, all in all, use it as a place to hang out, but don't at all consider it a church, and put your filters on to disseminate through what's being taught, not all of it is even the truth at all.
Pros: Good Music
Cons: Not a lot of substance to their message
