So, I watched the Desolation of Smaug, and I have to say that I enjoyed the filler. I have read the Silmarillion, The Hobbit, & The Lord of the Rings. I have yet to fully finish the Silmarillion. But, I must digress to the point to which I am miffed about. I really did like the movie, but I have a continuity problem with how The Hobbit: An Unexpected Journey (THAUJ) correlates to The Hobbit: The Desolation of Smaug (THTDOS).
Now, at the very beginning of THAUJ Bilbo and Frodo help us transition from the Lord of the Rings back to the very first emanation, which would lead up to the story that is the key plot to The Hobbit. This is awesome. It helps the non-readers of the books get caught up. BUT, why is that the Production Team had to make Smaug in THAUJ a fire-breathing-quadruped-alae dragon, better known to D&D fans as a True Dragon or in Literature as a traditional Western Dragon, and then in THTDOS we get to see his grand-malevolent-magnificence-under-the-mountain himself, a.k.a. Smaug, as an over-grown WYVERN? Is that much continuity too much to ask for?
Honestly, they can get all the little details about Thranduil's scars from Dragon Fire during the War of the First Age of Arda and the fact that Thranduil and Legolas are High Elves lording over Sylvan Elves, but when it comes to Smaug he's an overgrown wyvern. I honestly would have swallowed like soda and popcorn in a movie theater that they made Smaug into a wyvern if in THAUJ he had been a Wyvern, but in the first movie his front limbs were the first pair of a quadruped set not the alopeds of a wyvern.
To better explain myself. True Western Dragons are winged serpents, and serpents are quadruped lizards with snake like bodies, necks, and tails. In the case of dragons, Western Dragons are gargantuan, fire-breathing, winged serpents that have front, forelegs that sometimes can be used like hands but not always, hind quarters, and wings that mount on a second set of shoulders usually behind and/or above the primary shoulders of the forelegs.
A Wyvern is a lesserspecies of dragons, and they are mostly seen in Medieval Heraldry. But, they do not always possess the ability to breathe fire. Typically, a wyvern that can breathe fire is called a Fire Drake, which Bilbo did mention during his narration in THAUJ. Wyverns really didn't get any major game face in cinema until the movie Reign of Fire, staring Christian Bale, Mathew McConaughey, & Gerard Butler. There is is a significant anatomical difference between a Wyvern and a Dragon.
In the grand scheme of things, I have thought The Lord of the Rings & The Hobbit: An Unexpected Journey to be works of perfection. And, I haven't had any major pet peeves until now. So, in all honesty if people use this as an excuse not to go see the movie in theaters or discredit the movie all together then I believe you are just as "bark'n mad" as Gollem and just being silly. I just expect better from Peter Jackson & Company.
