I have seen it. It is the portrayal of a small group of Pentecostals and by no means represents Biblical Christianity. I agree with this reviewer:
"The second problem I had with the film is the way it portrayed Christians. If the film’s intention had been to show an impartial viewpoint on the modern Evangelical movement, then they probably would have shown an aspect of it that is commonly practiced by the majority. I am not going to get into a discussion on what is right and wrong about denominations or about certain issues among denominations, but most churches that claim the Evangelical Christian tag do not regularly endorse female ministers. So by showing this as a normal practice, you are suggesting that all Christians believe and support it. Early on in the film, Becky is seen leading the kids in a prayer in tongues. Once again, whether this is right or wrong is beside the point. It is not a practice commonly endorsed by most Evangelicals, and those who do practice it are much more private about it. By showing a room full of kids writhing on the floor and speaking in tongues, it is suggesting that were one to walk into any church in America on any given Sunday, this would be considered a normal thing.
And my final problem isn’t really with the film itself, it’s with the issues that the film brought light to that I had never really paid much attention to. I have to admit, I feel sorry for the children portrayed in the film. They all seem like wonderful children, yet I couldn’t help but think that this whole experience for them is just one big emotional roller coaster. Emotion can be a very powerful thing for adults, but for children it takes on an even greater influence. The children in the film don’t really speak like normal children; don’t act like normal Christian boys and girls. They seem to be speaking like their parents, and at times, for their parents.
I have no doubt these children desire a strong relationship with God, but I fear from my own experience that if these children base their faith in Christ on an emotional whim or a feeling they get during a powerful event, they could be in for some trying times when those emotions go away."
