Splash Mountain, a Disney ride based on a controversial film, will be 'completely reimagined'
They’re taking out references to “Song of the South,” replacing it with a “Princess and the Frog” theme. What a great idea.

I never saw the movie, but always sort of wanted to (prior to the increasing controversy), because this song always made me smile as a child. 
My understanding is the "vernacular" speech was a large part of the stereotype that many/most found offensive. Having not seen the movie, I can only assume there were scenes more pronounced than this or language far more overt: (?)
The star who portrayed Uncle Remus was Jimmy Baskette, a former Broadway musical actor who played with Louis Armstrong and in productions with the great Bill Robinson. Baskette was the first black male performer to receive an Oscar, receiving an honorary Oscar for his Uncle Remus portrayal in 1946. It seems sad his most famous portrayal ended in controversy. He was a talented singer, actor and musician. Sort of ironic that Hattie McDanel, the first African American woman to win an Oscar (Mammy in Gone With the Wind) in 1939 likewise suffered from the controversy of that portrayal.
