I honestly didn't mind the second Hobbit movie. Don't get me wrong, it wasn't amazing, and butchered a lot of J.R.R. Tolkien's work, but I don't think these changes were as apocalyptic as everybody claims. Not that they were changes for the better, but I don't think they were that much of a detriment as they're often claimed to be. Yes, the filler was annoying, and yes, adding Legolas in was a bad idea. But ultimately, it's still a decent movie. The plot wasn't anything groundbreaking, but it still followed the major themes and was fairly engaging in its own right, the effects were good (Excluding the molten gold), and the performances were well done and appealing.
I agree that the plot was decent, but they just butchered too much of Tolkien's stuff for me to be OK with. Heck, the Two Towers movie looks tame in comparison. Case in point:
-Beorn scene where Gandalf stalls long enough to get all the dorfs in was completely removed and replaced with random chase because Beorn is a dick in Peter Jackson's mind
+Pre-elves Mirkwood was good
-They brought in Legolas and Random Elf Woman Whose Name I Can't Be Arsed To Remember just to cash in on Orlando Bloom's popularity and give the film a female lead
-The river & barrels scene has 100% more elves and orcs
+The bit where Gandalf goes and checks out Dol Guldur was a good replacement for the White Council that happened in the book (although I will never comprehend why they randomly moved that to the first movie and made it so that Gandalf just left the dorfs on their own instead of coming along like in the book)
+Bard actually does something, which I'm OK with because at first when I read the book I thought a random musician was killing Smaug
-Lake-Town scenes are way too long
+The parts leading up to the entering of the mountain hall were good
+The part where Bilbo chats with Smaug was okish for a while
-WHAT THE FUCK WAS THE GOLD THING ABOUT-Film ends on terrible cliffhanger
Case finished.
