Man... if people were upset by the ending of the first movie (of Lord of the Rings :3;), then they're going to be REALLY upset by the ending of the second, if it follows the second book. I can't really say anything out of courtesy to those certain persons who may be reading this who have not yet read the books and intend to, but it's like this: the first movie's ending leaves you thinking "What? Wait! What next?" and the second (like I said, if it follows the book) will leave you thinking "OH MY GOD you did NOT JUST END IT THERE." XD
