I liked it.
You are wrong. You disliked it, you just didn't know it yet. Let me count the ways:
1. Shitting all over the introduction to Beorn. Seriously. Why. Why would you ruin a perfect comedic scene, only to tack on your own shitty comedy in other parts.
2. Getting caught by the elves. You ruined Bilbo showing himself to be clever by fucking around with the spiders, and then you also ruined another funny scene with the dwarves trying to eat at the banquets, only to be finally caught. Instead you have a cheesey action scene with Legolas in it. This brings me to...
3. Legolas. Literally everything to do with Legolas in this movie could be cut and nothing would be lost. Legolas was not in the book. Tauriel was not in the book. Fili did not fall in love with an elf. If we had cut this shit we could have done Beorn and the Spiders right.
4. The barrel scene. Once again we fuck up Bilbo being useful to tack on an action scene. If one hadn't read the book this escape would come across as a total ass-pull, and all the shots leading up to it did a truly horrible job of explaining what was going on.
5. Bard was not a boatman, the dwarves did not need to be smuggled in to Laketown. Why would you do this? To make Bard seem like a cooler guy, and get some populism going? He's the son of a fucking lord, he should be noble and terrible in the old sense of the word.
6. The Black Arrow. Just why? Why did this need to be done this way? It was better in the book. The "windlance" was cool, but hardly necessary.
7. The Smaug scene. I liked his voice, but the Scooby-Doo style chasing was totally wrong, and only served to ruin the tense atmosphere of Bilbo's interaction with Smaug. I did like his animation, though.
8. The forges. Goddammit, the specific heat capacity of gold isn't that low. It would take forever to melt those pots. Then, where did this fucking mould come from? How does gold cool that fast? Since when is Smaug dumb enough to get swamped in gold? Seriously, what was the thinking behind this entire encounter? I was thoroughly displeased with the whole climax.
5/10. Decent fantasy movie, poor
The Hobbit adaptation.
