When Disney chose Pocahontas as a historical figure to turn into a happy cartoon, they opened a can of worms. I mean, the movie is alright, but has no connection to the reality that Pocahontas went through and how traumatic it must have been.
"Anastasia" is sort of along the same lines. The story takes place in a much more recent time, but is still very much about real people. Yet, it feels more like Don Bluth got it right. Some things are wildly inaccurate (like Rasputin being a zombie), but it comes across more like a fanciful what-if story than any attempt to whitewash history. I suppose one might say they conveniently ignored almost all of the Russian Revolution, but this is a story for kids after all.
