Though the fantasy genre lends itself especially well to animation, some of the best animated fantasy movies have flown under the radar and don't get the attention they deserve. Since fantasy stories often incorporate wizards, warriors, dungeons, dragons, and mythical realms where anything can happen, it makes much more sense for such things to be brought to life in an animated medium as opposed to live-action. Because of the genre's versatility, all types of different fantasy stories have been presented in animation, from family-friendly fare to more frightening and adult-oriented tales.
