So here's my thought on why the movie is the way it is in regards to barely being about Eternia/He-Man and more about the Earth heroes. After reading the Slashfilm article they were talking about how important it was for the toy He-Man to make little boys feel power (hence the "I have the power" catch-phrase). So my theory is that the movie was made this way in order to have kids be able to connect with He-man and his friends/enemies more intimately. In the film, He-man comes into reality and makes the ordinary people the heroes of the story. Little boys could imagine He-man coming into their lives and fighting along side of him. They had the power to control the outcome of the story much like they did when they played with the He-man toys. Either that or a Steven King coke binge. All I know is, I saw this movie when it came out as a very young child and thought it stunk. I spent most of my time trying to reconcile the fact that Gwrildor is essentially Orko.
