What happened to real disney movies?

what happened to real disney? nothings like it was with sleeping beauty dumbo cinderella bambi the little mermaid........now they have movies like up or lilo and stich (not that there bad movies but i myself dont consider them true disney) i miss the old movies like lion king....movies today just dont have that whole disney feeling and most dont have anything to do with anything for example pocohantas was based on a true story, things just arent the same even disneyland there is barley a disney theme anymore
