This is a great example of a movie without any special effects. The majority of this movie is two people having a discussion. Although it appears to be a simple story, the subject matter is far from simple. I will not say that this movie is heresy. The goal of the movie is not to destroy the Catholic faith. Most of the cast, including Martin Sheen is Catholic. The portrayal of faith is present in the story, but on which side? The idea of a future Church where 2 more Vatican councils have taken place and the new Pope has denied the belief of Transubstantiation adds to the plot of the church of old and the church of new are at war. The discussion of what Vatican 2 did to the old Latin Mass and the church of old brings to the audience who only thought what they knew about the Catholic faith. What the Mass truly means is asked in this movie. The whole idea of the Eucharist is explained in hopes that some people may see the truth behind the Church. This movie is based on a novel that was equally controversial. Although this movie does not factual represent the Church, it does leave the audience with an ending that they have to interrupt for themselves.
