I watched K-PAX with my 11 year old Cousin.
She stayed with us during the summer and I had seen K-PAX a zillion times before and I was curious if my cousin would like it, so I sat her down and turned it on and she really enjoyed it, she asked some questions and was a little confused at certain points, I was able to explain it though especially when it talks about Robert Porter and his wife and child...but overall she really enjoyed it, even had her mother buy it for her when she got back home.
"Whoo! Whoo! Hey, Parny. I'm going to Chicago, baby! I'm driving a stick!"
