I suppose just because they were made by the Walt Disney Animation Studios, while the sequels, for example, were not... No one will remember movies like Meet the Robinsons anyway.

um well i dont know about you, but i dont consider tangled a good disney movie. i like it, but i think disney should be movies like Hercules and Snow White

The Disney Classics are the cartoon ones I think, not the Disney Pixar ones or the DC crap. Even though they may be considered classics, are they considered classics to you?
