Hate 'em. I deleted most of the precreated Sims from my game, primarily due to annoying celebrities, or my own Sims getting bitten by vampires. That and Vlad was constantly harassing my Sim. If it is a Sim I made myself, or downloaded from the gallery, and wanted for their appearance that MCCC turned into an occult, I immediately turn them back into human, and try to get their appearance back close to what I had.
There is no scientific evidence to support vampires (which is pretty much a legend that goes along with Vlad the Impaler's behavior on the battlefield), witches/'spellcasters' (in my opinion, "witches" were just misunderstood Wiccans), mermaids, or aliens (don't believe any of that BS you see on television--they keep making stuff up to keep that stupid show on air). Thus, from a realism-based player like myself, they have no place in my game.
