and can't say i disagree either. For one I think they could stay a bit closer to the book than having to run off on tangents that in fact are barely eluded to in the Hobbit book and are little more than a couple paragraphs in the appendixes. Yeah I think it is cool hey are exploring Gandalf venturing into DolGuldur and I really hope they include a bit of the Dwarf and Goblin war stuff. BUT I think they are overplaying the whole Necromancer/one ring situation which takes the whole purpose of the Hobbit story into a direction that Tolkien never would have wanted it to go. I just think to over work that part of the story to try and "fit" the LOTR trilogy together with the Hobbit films instead of letting the viewer use their own mind to figure things out is terrible. The beginning of FOTR tells Sauron's story and all we need to know about the ring and I know people don't want to believe it but there are people out there who have NOT seen the LOTR trilogy, to keep pushing the ring issue ruins the context of what the ring was in the hobbit story, A TOOL, and nothing more. The ring never spoke to Bilbo, it never invaded his mind, he never seen the dark lord while wearing it, the nazgul never hunted Bilbo because of it. It made him invisible, thats it NOTHING MORE. Sauron was hiding, was NOT actively looking for it in the open and didn't even declare himself openly for another 10 years AFTER Bilbo returned home to Baggend...
The character in every cast list is only ever referred to as the Necromancer, Benedict Cumberbatch has stated he is only VOICING the character. So thinking logically about it, and NOT trying to put any wishful thinking into it, I don't think "Sauron" will make an appearance in the fiilms as anything more than the necromancer or at least I am hoping so.
I think PJ and crew should stay as close to the book with very few variations from it as possible. I still do think the whole White Council stuff is cool but doesn't need to be half a movies worth. If Gandalf disappears for a while in the films thats fine with me. If the Necromancer is nothing more than a 5 minute scene thats fine with me too, its just a bit of icing on the cake but its not needed. too much about the ring being the one ring will worsen the film IMHO (cause thats not what the hobbit is about). Too many changes makes the story something its NOT, if Jackson changes too much they might as well change the name of the films and NOT call it the hobbit. Call it "more from middle earth" or something then.
Don't get me wrong, I think LITTLE scenes of backstory like,Thorin escaping Erobor, Thrain giving Gandalf the map and key, Dwarf and Goblin war stuff, Azog killing Thror and throwing a dwarf head with his name carved into the forehead back at the dwarfs, Azog's head on a stick after Dain beheads him, Smaug wrecking Dale and taking Erobor from the dwarves, stuff like that which is pertaining to the story at hand, which is the story of Bilbo joining a group of Dwarves to reclaim their halls under the mountain. It's not another story about Sauron, or the ring, or the rightful king of Gondor, or destroying a ring or anything like that, its about Bilbo and the 13 dwarves going to the lonely mountain. It seems people keep forgetting that.
Change is unavoidable going from book to film but it should be minimum when it needs to be done
