The Polka King was a solid, enjoyable film. The cast was great and was very funny at times. Jack Black did a exceptional job in this film and carried it to being a good film.
The only trouble I found was the dynamics within the story. There were moments I was plugged in, and moments that felt dry.
Other than that, I felt invested in the story and had a good time with it!
A good film to watch if your schedule is free.
