WARNING: I thought I'd watch HIGHWAY TO HAVASU to at least see some shots of a beautiful area where I used to live. I couldn't finish watching the film. WHY? Improbable plot. stupid dialogue. verbal and visual jokes that fall flat and are unfunny. Characters created by terrible actors trying anything to be funny and failing miserably. And most of all: horrific overacting by the leads and most of the supporting cast. LOUSY MOVIE! YOU HAVE BEEN WARNED!
