I am a fan of the Mutter Museum and now I find myself looking forward to seeing this new exhibit. One of my favorite displays is the eye injuries, they have more than just a sharp stick in the eye, all made in wax. By far I find it one of the least unsettling of their displays.
If you are going to see the Mutter museum and some of the other museums, you should get a combined ticket. We were just in Philidelphia but didn't have time to go to the Mutter but we still picked up the combined tickets, as they are good for a year. (If you were wondering we combined tickets for the Mutter and the U Penn Anthropology Museum, i'd wait a week or two from now before going to U Penn, they were in the middle of changing exhibits and rotating statues).
