the mid60s was such a bad time for American made movies that Meyer's 'Faster Pussycat Kill Kill' may be the best American film of the early to mid 60s. Either that or a couple of Sam Fuller films.
Hell, the mid-60s were so bad that even "Major Dundee," Peckinpah's worst film, seemed like the Godfather compared to the tripe that tinseltown was producing.
