If you are a coaster person, this is a downgrade. "family thrills" is not for everyone. Some people want to be turned upside down, thrown about in the air and at high speeds. Think of it this way, if Cedar point were to announce they were taking out Millennium Force for a family ride, people might burn the park to the ground. Hell you could tell people that they were putting FJ in for MF and people would still be mad. Whether or not the new Potter ride will be better for the park isn't really relevant. Some people will always prefer a real coaster.
