I remember hating a lot of little things from the original trilogy when it came out. At the same time I used to have this joke going on where I would still "hate it" after the 10th viewing in a month. Even today, there are a few things that irk me when I watch them, but I just roll with it. That feeling prepped me for this movie too, knowing that there would be things that would irk me, but just enjoy them for what they are.
I surely like the LoTR trilogy much more than the Hobbit, but I think many people forget how they really felt after things like no Tom Bombadil, Scouring of the Shire, Healing Houses, etc. etc, etc. I think where I feel that the Hobbit really fails compared to LoTR is that adapting LoTR is understandably difficult and an enormous task, yet what PJ gave us with that, though not perfect, was a fantastic job. The Hobbit however shouldn't have been as difficult to adapt, and yet we end up with some bizarre choices that many don't think should have even been considered. It wasn't the special effects, it wasn't the fact that The Hobbit is not as climactic as LoTR or the tone is different, it's the choices that feel like they were made behind a studio executive chair for the sake of business and audience baiting, and not the choices of someone who wants to adapt the story the very best he can with what he has. But it's done. At the end of the day, this movies don't corrupt my personal enjoyment of the books and story. I do enjoy them for what they are, and I'll just keep rolling my eyes and groan at the parts that irk me.
