Yes I am very excited.
Whilts a prequel (of sorts) this is a stand alone story and I cant for wait to see Smaug the Dragon in all his glory.
The fact that where going to see Gandalf, Gollum and the rest on the big screen again is fantastic.
Yes it will look spectacular that's one thing no one can disagree with. I'm looking forward to seeing Smaug the Magnificent in all his glory too. I don't think I've ever seen a dragon in a movie that I really like. The Dragonslayer one was pretty good for its time though.
