Corrected entry: There is one nag about one of the side characters: The goblin who later turns out to be a gnome seems to be a good friend or even relative of Snowball, but it is never explained how he ran off and got mixed up with the minions of Darkness in the first place.
Corrected entry: This movie inspired and sparked the birth of the famous and popular Nintendo adventure game series 'Legend of Zelda'.
Correction: This is just wrong. Shigeru Miyamoto is heavily credited with creating The Legend of Zelda story. Check his bio here: http://www.miyamotoshrine.com/theman/bio/index.shtml Nowhere does it mention this movie provided any inspiration for the game.
Correction: Not explaining the history of a random minor character is hardly a mistake, it wasn't something that would have aided the story to be explained.
