I feel like all of this background stuff doesn't matter to its quality as a film if the plot/characterization/etc. present within in the film can't stand on its own though. It's nice that there was a lot of thought put in that informs the movie, but ultimately a movie should not require supplementary reading to be enjoyed/understood fully.

Don't get me wrong, as a super-Tolkien-nerd I loved the Hobbit and while it had some pacing problems I don't quite get the critical hate, but I think his central argument is flawed.
