I think it is a must watch the movie. I personally believe that if you have a little knowledge about Christian Catholics you will understand the movie even better and why don't you go and Watch it by yourself. in fact, why to have the opinion of someone else when you can have your own, I mean that this world is full of beautiful creation of God and if you don't do something just because of listening to others experience, which you might have actually loved, that's honestly worst. so, do go watch the movie.
