They are showing only one movie? I never saw a cinema like this. I used to go a tiny cinema in Cracow that 2 screens sitting maybe 10 people each but they still had different movies at the same time. This is the one I go to now: https://cinealbeniz.com/ It has 4 screens, tickets are 6 euros, they never show any ads or trailers, I never saw anyone buy popcorn there. There's a whole network of cinemas like that: https://www.europa-cinemas.org/en/cinemas/map
