It's entirely possible that sending the audience out feeling lousy was intentional

The biggest problem with this movie is it’s a little better than you think it might be, which somehow makes it worse. As in, it takes itself a bit too seriously, which makes most of the movie feel kind of dull.

The story, direction, characters, and writing/dialogue is akin to taking a tranquilizer shot to the neck, but everything else was so well done.

It's easily one of the freshest, sharpest and most enjoyable films of this year.
