I'm honestly not a fan of fairies, especially the pink, sugary-sweet, glowy-winged fairies that Supernatural had.
I get that The Sims has a predominantly young, female audience nowadays, and as a 30-year old man I'm no longer the target audience, and that's fine, but TS3's fairies were just too girly. Same with mermaids and unicorns, tbh.
I'd prefer if they kept the supernatural content to stuff everybody can enjoy. Like with Vampires, we have Vampire Diaries and Twilight vamps if that's your cup of tea, or you can have monstrous, evil, bloodsucking fiends.
If TS4 had fairies that were more like elves, and we could choose between high fantasy, Peter Jackson prettyboys, or creepy Faire Folk that abduct Sims that step into their mushroom rings, and replace children with soulless doppelgangers, I think I could get behind fairies.
But the way they were implemented in TS3 is too polarizing, as it only appeals to one subset of the playerbase, large though it may be.
