When the normalization came, it came with strong censorship; most films that were shot were tv crime serials, crime films, dramas and "comedies". Censorship alone wouldn't be a problem, but most directors that were allowed/wanted to shot were somewhat pro-stalinist or Joes, or simply adjusted themselves to normalization.
Bláznova kronika is comedy, so I'm listing all my problems with it that haunts todays czech cinematography.
The actors act like if they are acting stupidly bad on purpose, there is no truth in their masks, they forceplay their roles. It resembles some shit plebeian greek comedy. It's not funny. It's vulgar.
It panders to the lowest common denominator. It shows the lowlinnes of masses and panders to them with muh common sense and muh ordinary people are smartasses that always outsmart those above them, in this case le evil royalists/aristocracy/military.
common sense is bullshit, it's mere glorified myopia
The language used is awful. Maybe I wouldn't be against it if most very dumb people wouldn't be using all those smartass words, but it's common that you see people like that here in czech way too often. See above. There's nothing sublime in it. It's vulgar.
Not sure about how I should approach the comedy itself part, but it's all vulgar, too vulgar. That's why nobody in their right mind should ever read Zola, it's the same.
About camera, as I said before, I lack in vocabulary.
For reference see Troška, Poledňáková, Lipský, Svěrák, some films from Hřebejk, Menzel, Kachyňa etc. Especially first three and Menzel. The newer films you watch, the worse it should be.
post-89 is capitalism, so there's your answer
you have to sell, and making shit films is the easiest way
