This combination of fantasy, musical, extravaganza and silliness doesn't really work. It could be a brilliant satire, a "The Good Soldier Svejk"-like grotesque; it could be something similar to Milos Forman's "The Firemen's Ball", but, unfortunately, it isn't. The basic premise had the potential; the idea of turning guns into clarinets and vice versa was a good one. However, the directors were too obsessed with playing it safe in Communist Czechoslovakia and making the viewers "have a good time". In the end, silliness prevails, and the film doesn't live up to its cult status.
