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

There's no way I can possibly love it entirely but I just think its ridiculously bad, but enjoyable at the same time.

The film's masterful storytelling did its job. The message was clear. No need to overdo.

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