Granted I am not caught up with Supernatural as of yet (just started Season 2) and I am sure there are many other fairy tale themed episodes, but this upcoming one excited me because it sounds a lot like the Hans Christian Anderson fairy tale "The Red Shoes."
Supernatural (9 PM, The CW):This show is back, after an all-new Nikita at 8 PM. And this time, the Winchesters are coping with... magic shoes? Urk. Yes, the gimmicky plots just keep coming. A ballerina dances herself to death, and the cause turns out to be cursed ballet slippers — and then Dean accidentally gets hit with the deadly dancing curse. Here's a clip! (See original.)
While the person who wrote the blurb obviously is not impressed, it might be fun for us mythophiles.
