My problems with the
Hobbit trilogy are manifold, but almost all stem from two terrible decisions at the outset that trickled down into every other facet of the filmmaking: 1) the oft-remarked-upon decision to split a slim tome into three ridiculously bloated films, and 2) shooting at 48 FPS.
The decision to trilogify it was a financial windfall for sure, but creatively, it meant that the entire enterprise lost any semblance of focus, and was packed to the gills with a miscellany of plot threads, none of which really felt part of a central work. I get that Jackson knew neither he nor anyone else would probably ever return to Middle-earth in our lifetimes, due to Christopher Tolkien's Christopher Tolkien-ness. Wanting to take a victory lap
and do an end-run around the vagaries of intellectual property laws are both things with which I don't have any particular problem. But it didn't feel like Jackson's heart was in the execution of this go-round (something supported by the fact that he tried to not direct them, and only wound up doing so after being basically forced by the producers).
That second bit, the high frame rate, necessitated the junking of the practical effects that Jackson put to such sterling use in the first trilogy.
Here's a pretty good breakdown of the missteps caused by that single poor commitment.That said, the whole enterprise still held just enough magic, and was generally so damned genial that I can't understand those who hate it. Sure, it's a houseguest that overstays its welcome (by a substantial margin). But there are far worse films out there, and at the end of it all, we got a kickass dragon and an amazing battle sequence/film out of it. It's not ideal, but there are certainly worse ways to spend nine hours (
reading Tolkien comes to mind).
