I'm not a big MOS fan by any means, but I don't hate the film like some do or feel that it's a truly bad film at its core. All the pieces of the "MOS puzzle" didn't quite come together in the way that I feel they could (and should) have. I've realized there are actually a bunch of things I like about the movie individually, but the overall film lacks the proper synergy and connective tissue to properly bring those things together in a satisfying way.
Aside from the typical criticisms of MOS and Snyder we read on the Hype every day ad nauseam, the film is just missing something. If it had been stronger and more emotionally fulfilling in some places, I think some of those other shaky elements/decisions could have been forgiven (or at least ragged on less).
