Have you seen Sexmission? The film's biggest shortcoming is that it is short of originality, for Machulski rips off most of its storyline from THX 1138; he duplicates Lucas's flick brazenly to the extension that some scenes seem to be precisely counterfeited from Lucas's work. On the other hand, the movie somehow works in the context of Polish Pop Culture and on account of its highly politicised, anti-communist content as well as some epic jests. Nowadays, the film might be deemed as anti-feminist, but this allegation is totally extraneous since Machulski was not interested in excoriating feminists in the first place.
I'm not an expert when it comes to Polish cinema (I prefer Italian flicks), but I'd say that apart from some anomalies, Polish cinema was quite homogenous and it's foolhardy to christen these anomalies anyhow forasmuch as they're too marginal in their nature to be treated as an emergence of some brand new tincture.
Szulkin was a legitimately unique casus within Polish cinema, but as far as I know, he didn't yield any successors and so he cannot be pigeonholed as a member of some movement.
At any rate, I don't think there was such thing as 'exploitation' in Poland. If there was, I'd coin it as 'polsploitation' as it sounds more natural in Polish than rasping 'polzploitation'.
