"Storytellers for all times have taken core story material and adapted and changed it for their audience, their era, and their point of view. Giambattista, The Brothers Grimm, Charles Perrault, Hans Christian Andersen, every storyteller throughout time. To say that we 'Disneyfy' something as a pejorative in terms of adapting a narrative is to reveal one's complete naivete' about the process and history of storytelling." -- Thomas Schumacher, Disney Feature animation Vice president.
What I am trying to say is, it's OKAY to take a classic tale and give it your own interesting imaginative twist to it, some people don't as they feel that it would be sacrilegious to the source material but the truth is the source material may not even be the Source as it too may be a modified version of a previous tale. This year I plan to do two one-shots one will be my take on the Seven voyages of Sinbad and the other on the Folk tales of the Russian witch, Baba-Yaga. They're not going to be true adaptions; far from it, even one I'm setting in Space. But it's okay to do that, you're not in the wrong to do so, in fact you might be more creative by doing so as you are at least thinking up new and possible interesting new spin on the same ol' same old tale.
So in short, if you always wanted to do a tale of Robin Hood under the sea or Anansi the spider as a African business man who battles Robot in some cloud city, go for it and DON'T let anyone tell you otherwise.
