It is rare that I recommend movies to anyone. To me they are simply a form of entertainment, nothing more. However I do want to recommend "Religulous". Wikipedia describes it as a 2008 American comedy/documentary film written by and starring political comedian Bill Maher.
Bill looks at all religions in this film, while searching for answers to his own questions about God and religion. Some of the questions I'm sure many of us have. In his own satirical style, the final film gives us the perspective of religion from an "outsider looking in" point of view. Bill is doing for religion what Michael Moore did for health care. A real eye opening experience!
