Just found that Poster of "Lemonade Joe" (the head line says "The West has never been so wild before!" ): 



You're probably right about the artistic similarities between Chytilová and Makavejev, A was also of the opionion that "Mysteries of the Organism" was similar in many ways to "Daisies". 

When I was hard core watching Czech films I simply watched everything I came across without following any recommendations or reason behind it. 
I'd even say that's the best "technique" but if your time is limited and you're not patient enough, you hardly manage to go on like that (and without a rental store like Facets around the corner - who would by a "suspect" film?). Many people avoid reading anything about a film before they watch it - sometimes, it would be great to be like that because clearly specified expectations are rarely advantages.
