That is true, I love the competition TSM causes between my wife and I, she is rarely competitive but Mania brings is out of her. She doesn't care for Buzz though. I thought of Mania as a gimmick when I first rode it, but now it is one of the most memorable rides in HS for us because of the fun we have.
The only attraction that is more memorable for us in HS is the Tower, that is because we discuss different poses before we ride.
My point is as long as Disney doesn't flood the parks with the same type of ride, in this case as you call it, a screen ride, than I think it could be a classic. I feel that that is where Universal went wrong with their 4D rides, they have a half dozen of these with the same basic ride through just with different images.
