Superhero McPlayland is a little much, but my point is this does all of the following
a) This caters to the next generation of disney goers
b) This appeals to not only them but to everyone since this is a product that has been around for decades
c) This is an IP that is not only hot now, but has been for years and still will be for years to come
d) Most importantly, this is an IP that can be used in conjunction with the edutainment rides Epcot is known for
These are characters that 20 years from now people will still know who they are, just like Star Wars, classic Disney characters, etc.
