Although it has its amusing moments, in eneral the plot does not convince.

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

I really wanted to like this movie. I feel terribly cynical trashing it, and that's why I'm giving it a middling 5. Actually, I'm giving it a 5 because there were some superb performances.

There are moments that feel comical, some horrific, and some downright inspiring but the tonal shifts hardly matter as the end results come to a film that's perfect for this time.
