It seems an odd thing to market–if you read the books or saw the first three movies of course you’ll see the final film. Even if the third film wasn’t so great. But the recent round of content has me wonderinf if perhaps the movie has a surprise in store and will change the ending from the books. Read after the break to explore this theory.
