I went to a camp like this, as well as school and a church, in my childhood. The emotional manipulation sucked, as you would expect, but give kids credit for having some powerful internal stabilizers: I’m now deeply agnostic with no particular hostility towards religion; other friends of mine with similar backgrounds range along the complete (Christian) religious and non-religious spectrum.

As far as the documentary itself: Of course it has to be selective to make its point, and the disturbing nature of the adults’ behavior in particular is not, I think, too distorted. Overall, it’s a good and accurate film, if its case is a bit overstated.
