How does this church compare with the traditional evangelical church?

So I went to a church today called The Church in Dallas (maybe it was "of Dallas"- don't really remember) In it's brief history from the church's website, it talks about how they started after reading something written by Watchman Nee. I read a little about him, but it's hard to sift through. The church seemed a little cult-like (people all speaking instead of one pastor, the congregation saying "amen" after pretty much EVERY sentence that is said, they meet in a circle instead of looking towards a stage). The doctrine from TODAY's service seemed to be pretty much along side what the Bible says, and the people are really friendly, but can you see anything wrong with it? Do you know anything about Watchman Nee or this particular denomination that may conflict with my evangelical (actually baptist) background?
