I think that none of the "Leopolds" are honestly that great (despite some things like the music indeed being quite well done), but this is probably one of the best ones. It feels like the crew had got the whole process down pretty well by this point. It's also the only one with a distinctive theme/setting that its main competitor (Soyuzmultfilm's "Nu, pogodi!"/"Well, Just You Wait!"), for whatever reason, never touched on.
