Great cast. Sometimes everything comes together and works but, most of the time, it varies weirdly between cringey, hilarious, boring, touching, and cheesy. I admire the effort (A+), but I'd have rather not wasted my time.
Logic can be used to solve problems, but it cannot suggest which problems to try. No one has ever formalized significance. To recognize what is significant you need a certain amount of experience, plus that elusive quality: intuition.
Still the greatest road movie ever made.
