I like the IPs because I can get the back story before I walk through. I go with a group of folks and we have several viewing nights to get ready for HNN. I wasn't comparing houses, just the IPs themselves and the excitement around them. But you are right, knowing and loving an IP could lead to a bigger let down. I really liked the CitW movie and couldnt wait for the mermaid, but was kinda let down by it. Still was a great house, but the mermaid was just funny.
