There is at least one cult version.
The International Church of Christ (ICOC) http://www.icoc.org/

the Christian Church of Christ is non denominational
In my experience, I have never been controlled or brain washed, although, there have been times that my mind needs a good washing. Over the years, the ICOC has grown and changed as needed, and has seen some bad times, but also some very good times.
The amount of lives that have been changed for the better, through the ICOC or through its benevolent arm, HOPE Worldwide, across the country and around the world has far outweighed the criticism that some give.
So...in my opinion and experience...not a cult. Although, first century Christians were also called a cult, so maybe it's not so bad.
