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

it is finally so absorbing because it plays like a lyrical road odyssey that’s also a detective story.

I enjoyed watching this film and would recommend other to give it a try , (as I am) but this movie, although enjoyable to watch due to the better than average acting fails to add anything new to its storyline that is all too familiar to these types of movies.

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