Actually, Buffy the Vampire Slayer and its spin-off Angel mixed both sci-fi and fantasy features well. They had biomechanical demonoids, curses and spells that could be activated with help of advanced technology (or conversely, epidemic plagues of scientific roots but are activated by magic), translating interdimensional spells as mathematical formulae, meteor-dwelling demons as "extraterrestrial hostiles", and technology that could hamper and dampen supernatural beings and/or artefacts. I retract from my previous stand on this--I don't mind Sci-Fi in a dark fantasy setting but it needs to be done well. Unfortunately, for Supernatural, there is very little to no precedent to suggest a good mixture of the two related albeit different genres.
