For all the hype it got I was expecting a lot more!

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.

It’s fine. It's literally the definition of a fine movie. You’ve seen it before, you know every beat and outcome before the characters even do. Only question is how much escapism you’re looking for.
