A brave move on the Pythons' part to try a comedy about religion. In spite of the heretical humor it is fairly historically accurate in many ways. There actually were many self-pronounced "Messiahs" in the era of Jesus and rebel groups trying to overthrow the Roman puppet government were common. That being said, this is one of Monty Pythons better films and certainly worth viewing. There were a lot of protests from Christian groups due to the subject matter and so a lot of people boycotted this movie. So go rent or borrow this movie and see what the controversy was all about.
