Made in 1989, a few years after Dead Man's Letter, this film contains some similarities: a post-apocalyptic world where civilisation has collapsed, in this case because of ecological catastrophe. The ecological catastrophe is the result of man's careless treatment and overexploitation of nature. All that remains is a barren landscape (not a tree to be seen), pollution and lots of rubbish.
Like the earlier film, it is shot with a very limited colour gamma, mostly dark reds and blacks. I found it easier to see the point of Dead Man's Letters. The Museum Visitor has several very powerful scenes, but it is harder to se it as a coherent whole.
The film's hero is a "tourist" who travels to see a museum that can only be reached when the seas part. He is one of the few human left who still keep the old attitude and way of thinking. More numerous are some kind of mutants or idiots (most indeed played by people with real disabilities) who live in reservations in some kind of permanent religious exaltation. Normal, intelligent humans are sceptical atheists, and keep the idiots away, inter alia by lighting fires on their windowsills. However, even the normal world has been turned upside down, and thus for example the new fashion dictates that men wear high heels and tights. An old man at an inn asks the tourist to close his eyes and open the scriptures at random and point at a paragraph. But nobody is able any longer to understand the meaning of the scriptures. The world is too far gone, too close to the end to be able to appeal to any gods.
While trying to reach the museum, the "tourist" undergoes a profound deep transformation and ends up on his own via crucis.
I would hesitate before recommending this very tough, depressing film, except to those who have enjoyed other films by the same director.
