Never read the books. But the anti-fascist shit, and especially the anti-cathloic notions, if even super subtle, always piss off the die hard catholics. Hell, people got so worked up over Harry Potter, and that was so far from blatant its not even funny (some school districts banned it because it was like devil worship/witchcraft shit).
I saw the movie on Monday, and its not that good.
If the book caused a stir, the movie hardly will; it is so dumbed down. Too quick, too dry, and relied too heavily on special effects. All it turned out to be was a prelude to the next two, meaning it was super anti-climactic. Overall, it seemed like a bad book adaptation: too often there were these blunt statements and shit that were clearly meant to explain what was in the book to the viewers, which was almost certainly more explanatory and subtle, in the way a book can provide. In the end, I didn't give a shit.
