I go to movies to be entertained, not to analyze and critique. There are certainly plenty of movie critics online if you want that take on a movie.
Maleficent is not great but it certainly was entertaining from my perspective. The film takes place in a fantasy world so events and people don't always behave how you might expect.
This is the untold story of one of Disney's popular villains, Maleficent from Sleeping Beauty. We watch her as a young child explore her world with an open, pure, heart - welcoming, trusting, and loving.
