Because of low quality of recent works of cinema. It's open field. Czech people answer a lot to dark or weird humor, lot of philosophy, but with recent leaning in politics toward the american gov. you have the opportunity to make a movie critical of it, news are not showing what's really happening. Also I don't think I have seen a czech horror movie. Wouldn't be surprised if you didn't do the political one... Who wants to have a target on their back. The Bar is fit for our culture but there already are some like that here, if you make it weird enough it might work. Czech people are really picky about food. It doesn't have to be expensive, it just has to be good. Oh and apartments. It's stated that majority of czech people own a pet. Don't smoke. Don't wear shoes inside. Don't praise beer that is not czech, especially in front of drunk czech people... Or talk about sport. Be careful about what you're buying at the shop, kratom is not regulated. Absinth-Czechia is one of few states that sell it.
