Those are some of the reasons I think it looks like a good film - traditions of man being revealed for what they are, not of the Bible.
Since the Church determined the canon of Scripture, I suppose you would have to toss out your Bible as a "tradition of man" as well. Sacred Tradition and the Scriptures are part and parcel of the same divine revelation by Our Lord to the apostles and handed down in the Church. They are not "traditions of man". And a Merry Christmas to you too... ( or perhaps you view it as a "Devil's holiday")
To which "traditions" are you referring?
