Some theaters removed the film from the repertoire. A worker of one of those cinemas explained: "We withdrew Kac Wawa because we couldn't sell the tickets. People would leave the cinema while the movie was being shown. After that only one or two people would turn up. We figured we couldn't afford to keep this movie in the repertoire."
Polish critic Tomasz Raczek wrote in his review:
"So I came to see the movie KAC WAWA and I've got to admit, I don't remember the last time I felt so embarrassed at the cinema. This isn't just a bad movie. This movie is like a disease, like a malignant tumor: it kills the faith in cinema and respect for actors."
Producer Jacek Samojłowicz sued Raczek, saying that "according to [his] lawyers, [Raczek] has exceeded the limits of film criticism and breached journalistic ethics, perhaps for personal reasons."
The film's screenwriter, Piotr Czaja, confronted Raczek, accusing him of having failed to understand the message of Kac Wawa. Czaja also stated that he had been given the impression that the viewers liked the film and laughed a lot.
On his Facebook profile, Szyc wrote: "Critics are one-legged theorists of the broad jump. It's easiest to just criticize; especially we Poles love it."
