I totally agree with the above comments. I loved the educational aspect of each of the rides. I would have loved to see Habit Heroes, and i think it would have been an improvement.
Other than the financial dilemma that Disney will or will not take responsibility for in updating or creating rides, some of the public today seem to get uptight as to where or how they want to be educated. We saw this happen with Habit Heroes, and may also be a reason for the closure of Wonders of Life. For all of the institutions pushing for higher learning and better success in education, there seems to be a continual dumbing down of the values necessary to provide for learning. It seems that some only want to be entertained, and that's it. We can see this through entertainment in all its forms, not just at Disney.
With that thought in mind, i believe there is only so much that Disney can do when creating new attractions...the creativity is already squashed by the thought of "who's gonna find fault with this attraction?" and "Do we want to spend x amount of dollars on something we may have to back out on?"
I don't mean to get all philosophical with this, it just seems that the generation we live in today makes it difficult to allow for the attractions we once had 10-20 years ago...especially where healthcare is concerned.
EPCOT does need some tweaking, just not sure how they will do it.
