This adaptation takes a lot of liberties with the story from the book, which is certainly common enough and can lead to a more entertaining film. However, in this case, the seminars seemed facile and facilitators were caricatures, almost laughable rather than menacing. It's much more clear in the book that the point of conversion therapy is to crush participants' self-esteem and replace it with a slavish adherence to fundamentalist ideology. It is brainwashing, intended to destroy independence of mind. The "therapy" is truly scary and I don't think this was captured well in the film.
The other aspect of the book that is mostly missing from the movie is Garrard Conley's interior dialogue. The plot of the book is actually pretty thin; Garrard's
self reflections and his insightful portrayals of the other participants make his book far more moving than the film.
And finally, the film ends with Jared's confrontation with his father. The movie makes it seem like the cowed teen is finally standing up to his tormentor, the author of his tragedy. In the book, I never perceived that Garrard ever views his father with anything other than love and respect, as a person of sincere and deeply held views. His book is dedicated to his parents. You wouldn't know that from the final scene in the film.
