Antonioni's ridiculous "Zabriskie Point"easily the biggest turkey 
from a major director,that wonderful sound track(Grateful Dead,Pink Floyd,John Fahey etc) is the only redeeming feature.Being An old hippie with a haircut this pile of crap gives us old bastards a bad name! 
Ps i hardly rate "Oliver Stoned" as a great director but he does make some horrible films.
