Maleficent is interesting because its central thesis is that the prior Disney movie, Sleeping Beauty, was basically just lies and propaganda. So it avoids the usual mistake these remakes usually make, where they try to "fix" problematic stuff by trying to plaster around them, while still having to indulge the central plot beats, and Maleficent comes along and is basically like "nah, it was all lies and BS", so they're free to restructure things and reorder things, and they only have to pay scant lip service to whatever events they decided really did happen.
