The Darker Side Of Oz
I think Disney's decision to make this movie was almost as bad as the MPAA's decision to rate it PG. Disney made this film in the mid-80s at a time in which they were about to have to relinquish their rights to the Frank Baum books back to MGM. The movie was plagued with problems from the very beginning and ultimately flopped as a result.
Despite it being a bad movie, this movie is not for children. Return To Oz explores the darker side of the Oz books, as exhibited in the second the third sequels. It begins with Dorothy being sent to a sanitarium for primitive electro-shock therapy in a vain attempt to get the thoughts of Oz out of her head.
Once back in Oz, she encounters an onslaught of antagonists including a princess (Mombi) that has a cabinet full of removable heads, a bunch of guys with wheels for hands and feet (the wheelers), and the Nome King, who is the mastermind behind it all.
Forget the light-hearted nature of the 1939 classic. This "sequel" possesses a darkness that would make Tim Burton proud.
