I haven't heard of
any Christian fantasy TV shows. It's sad, really. It's probably due to those being in little demand (at least, for the general unsaved public, and the point,which Melody Kondrael has pointed out already, that most of us don't get cable) and the fact that creating ANY fantasy is not cheap. Some fantasy series are made into mini series, as to save money. So, they don't have Christian fantasy shows, at least, that I know of. But there are Christian movies. and you can always curl up with a good book
