I saw the Book of Mormon. Where do you stumble with songs and dance numbers and most of the lyrics and points / parodies - except they talk too fast.
I see it and it was surprising with so soft perversified sequences about genitals and perverted life - realized that it was parody, but if some of the reviewers had read this, I would not like to talk to my 12 year old granddaughter. In my opinion, a shattering feature and very exaggerated to get points. A little sad indeed.
