Like everything else, it's a personal preference. Not all people think that something is nice. In fact, quite a few people have described my boudoir/art dolls as "creepy" and "scary."
So, when you collect anything, the important thing is that YOU like it. It doesn't matter what other people think. You're the one that's enjoying it in the privacy of your home. Of course, when you're sharing that home, you might have to endure the endless sighing and eye rolling when another doll arrives. Just make sure they all know that when "Mama's happy, everyone is happy."
