This is probably Russ Meyer's finest hour - a Tarantino style movie following a group of angry women, on a tour of random violence in rural California.
The violence must have been truly shocking in the day, especially as it is being dished out by women - in that aspect it reminds me of something from the
Clockwork Orange [1972] [DVD] mould, or if you look at it more recently - and much closer in style, it looks like a model for
Kill Bill 1 and 2 (Box Set) [DVD] [2003].
As opposed to Meyer's other movies, the sex aspect is relatively muted / in the background, so apart from the ample cleavage, it's all completely PC. There is plenty of double entendreing, which might have been risque in the day (in fact some of the dialogue would be right at home in the earlier James Bond movies) but appears mostly sarcastic, if seen from a today's viewers perspective.
The driving is largely comical (accelerating the camera a bit much at times), the acting is often completely indifferent (the pained expressions of all the women but Tura Satana when behind the wheel are a laugh out loud thing in their own right) but the whole plot and dialogue is relatively neat and overall it's good fun. In some ways, it looks like a spiritual predecessor to a movie like
Clerks [DVD] [1993] as well as the more commonly mentioned
Pulp Fiction [DVD] [1994] and while not passing over every theme of the day, like Meyer's later
Vixen [1968] [DVD] was, it is still a milestone in portraying the changing gender roles in the 1960s.
