A documentary isn't always about the "presentation" it's also about the story it tells. So you giving this movie a 1 star tells me you're just a hater. If you gave it a 5 I would of have taken your review in consideration, but seriously 1 star.
I knew about this pastor for many years and he and his wife are truly amazing people. They save unwanted babies with a question, doesn't that deserve at least 3 stars just for the story. What is wrong with you? Wow. Someone's got no empathy.
The reason no one in the audience clapped is because they were in awe. I'm sure the sighs were from yourself and your friends who critique simply things like camera angles and background music and not the story.
