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.

There is, somehow, an interesting story here, as well as some good acting. There are also some good scenes

The film may be flawed, but its message is not.
