A very quick look at the cast of this film shows that Stanislaw Tym - a legend that he is - is not the only professional actor playing in this film. Many of the actors are amateurs, adding a flavor to the atmosphere of the film, but majority of the main characters are played by professionals.
As a Polish person I find this film amusing but was never taken by the hype. It's difficult to say how many people genuinely love the film, and how many feel obliged to say they love it.
Rejs is a very "Czech" Polish film - free thinking, good spirited, weird and wonderful. You can watch it as a political metaphor or a social / philosophical observation of life.
What it does really well is make you feel being captive in an absurd situation. You feel the slowness, the time being taken from you when you wait for another bit of small-ish talk. In real life one can have a suspicion that the person nominally in charge isn't really in charge, and the guy who's pulling the strings is an imposter who wasn't even trying to get all that power. Why is your own inadequacy or persona supposed to be any worse?
