No spoilers ahead, only mentioning things you can see in the trailer .
this was a pretty mediocre Disney film in general. not bad by all means, but a bit like... unnecessary? maleficent is never the mistress of evil, or portrayed as the villain she was upon the original material, ends up being a bit of a bland version of a powerful villain recurring to sarcastic remarks here and there to make her relatable. it's not about the performance of the actors, is about how she was written. Michelle Pfeiffer came with a LOVELY villainess (an evil queen that totally fits into Disney's villains) to kinda replace the one maleficent was supposed to be, but in the end the movie feels a bit like a Mish mash of several ideas already seen and filmed. the whole idea behind maleficents origins was vastly similar to avatar, and not in a nice way, more like in a "I copied parts of your homework and branded as mine". I'm hoping they will start making original content soon, these reboots and reinterpretations are getting old.
