I know the movie since I was a kid but at the time I couldn't understand it that well... now I had another watch and I pleasantly surprised.
Please note that this movie addresses a very serious issue in Balkan societies, and although has some humor in it, it has nothing to do adult/erotic content (just showing how the movie is badly represented, which I discuss later a bit)
The movie was obviously very relevant for that time, but funny enough it is still relevant for the whole Balkan. The contrast of old, that is traditional, versus new, coming from West, is something that is always an ongoing issue and challenge that is discussed constantly in Balkan societies (in particular, ex-Yu).
The message of the movie transcendent two extremes depicted here, highly conservative Montenegrins families from mountains and emancipation that comes from West in form of the nudism. It can be applied on the discussion on gay parades, capitalism vs socialism, darwin vs church, etc. So 30+ years later, the same discussions appear. To generalize a bit, it is the issue of how much Balkan societies should bent their traditions, ie offer their butts, to please the West (nowadays Brussels mostly) in order to progress (economically mostly).
The movie is hard to understand, especially for people that do not have personal experience with the same issue, so I can understand that not many people cannot relate emotionally to the message of movie (I noted that there is very little reaction about it here and elsewhere on the Web). On the other hand, if Montenegrins/Serbs or whoever, cannot even make a proper wikipedia page about it in their language, why should someone from Sweden do it in English or Swedish, as an example. Also there is no a version one can watch online (unless pirate) that talks about preserving national movie heritage.
All those comments were about the context and message of the movie. I cannot discuss the picture/music quality, since the quality of the pirate version I watched was awful :(
