I am really looking forward to this, along with "Vikings" which will air right after.
From what the producers have been saying, I'm optimistic that it will not get butchered, which is what I first expected when I saw the first commercial for it. I never trust the media to get a single thing right when it comes to the Bible or Christianity.
However, the bastardized History Channel (and I call it that because there is so little history on it anymore) has actually done very well with their previous miniseries of this type (technically docudramas) and kept it on topic rather than as a propaganda piece. We'll see if that continues.
Of course, I've already seen some of the self righteous on another website trashing it with everything from calling it a sneak attack on Christianity to a pro-Obama propaganda piece.
