"I really couldn't care less what historyand science has to say about the events during Chirst's times."
You should. As the Catholic church says, when presenting any dramatization of the passion, there must be an "overriding preoccupation to bring out explicitly the meaning of the (Gospel) text while taking scriptural studies into account" ("Guidelines and Suggestions for Implementing the Conciliar Declaration 'Nostra Aetate,'" 1974).
Unless you don't recognize the authority of the Vatican, like Gibson.
But really, reading the bible alone without proper interpretation is dangerous. Many people have done that and used what they like from the bible to justify many criminal acts, one of them being the persecution of Jews.
Adolf Hitler praised the Passion Play at Oberammergau, declaring it "vital that it be continued for never has the menace of Jewry been so convincingly portrayed as in this presentation of what happened in the times of the Romans."
The bible can be used to ANY purpose, often evil ones, and often has in the past. That's why proper interpretation, and by recognized authorities, is important.
