In the best tradition of Soviet fantasy, Dikanka is entertaining from start to finish. There isn't much a plot (hijinks during the night), but the practical effects are charming, and I laughed harder than I had in a long time.
The best element is the Devil himself. Rather than a figure of fear and evil, the Devil is a hairy, silly fellow who keeps busy by tormenting a blacksmith who drew a religious picture that the Devil found particularly offensive. In addition, there are a horde of lusty and/or drunken townsmen, and a cameo by the Tsarina herself. Also, a "Three's Company"-esquire set piece where character after character must hide out in the local witch's hut.
