This movie serves no purpose beyond nostalgia for "Disney Adults". It's a gimmick version of the original, and brings nothing new to the table, ESPECIALLY 4 years after its release.
I couldn't imagine anyone making the conscious decision to show their kids this version instead of the original.
The fact that every 5 star review reads as someone saying they grew up with the original and loved it, is telling that this film has no merit on its own.
