As I am no longer a pro movie critic, I had to go see The Hobbit: An Unexpected Journey after it came out like a common troll (get it? Get -- ah, never mind). My local cinema had it at the standard frame rate, but there was a movie theater in Dayton showing it at 48 frames a second, which is director Peter Jackson's preferred frame rate for folks to see the movie in, as he believes it makes for a more immersive cinematic experience.
Scalzi's take on the Hobbit film. I'm pretty much in agreement with him when it comes to the 'Tolkien purist' bit.
