Movies aimed at children tend to be pretty wholesome and inoffensive. They rarely upset audiences with provocative content or controversial casting choices. And you rarely hear about banned kids' movies, excluding relics like Disney's Song of the South, which the company has kept from the public for decades due to its offensive depictions.
However, that doesn't mean films aimed at young audiences don't occasionally generate a little heat. There have been a number of controversial family films, many of which were released in the 21st century.
Reasons for these controversies run the gamut from unintended implications to depictions of animal mistreatment to concerns over children imitating bad behavior. In some cases, the outrage was justified; in others, oversensitivity may be to blame. A few seemingly innocuous children's movies have even sparked protests.
