I've always found this one of the better movies to have been riffed in The Mystery Science Theatre 3000. Unlike a lot of the other movies featured, this film is actually pretty interesting. It's very surreal and fairy-tale like, but that's what makes this movie so enjoyable. It also shouldn't be taken so seriously, due to the fact that it is intended for children. But Morozko isn't bad at all. The acting was much better than any other MST3K movie is, although I found that sometimes they went over the top. Also, some of the special effects were really well done, while some others were a little dated and cheesier. The only main problem I found when watching this was the awful dubbing. Other than that this is a fine, surreal adventure.
