Three members of our family enjoyed it. Myself, my wife, and my 9 year old son. However, my 5 year old daughter hated it. She didn't find much interesting and was scared at a lot of the exhibits. If you have younger children, or more timid children, you may want to gauge their reaction to some of the exhibits in the lobby area. If you see some concern in their faces, it may be best to skip for those members of your family.
Unless it's changed in the last couple of years, it's very interesting to some, dark and scary to others.
