[Fenris Technique]

The effectiveness of any aspect of story telling relies entirely upon the talent of the author. I think we could all easily name at least a dozen successful authors who write fiction containing supernatural elements.

And for each successful author we could find a thousand failed ones self publishing on Amazon . . . but it's not the decision to include 'the supernatural' that's killing their work. It's their crimes against grammar and deep seated aversion to MS Spell Check.
