The way aurora was awoken at the end was also very awesome. It would have been kind of cheesy if the prince woke her up with true love's kiss when he'd only met her once. But the love of a mother (sort of) for her daughter was shown beautifully here with a perfect emotional speech by maleficent before the epic battle ending. The dragon fight at the end, and the moment she got her wings back were both amazing. Also when she spinning-burst out of the window in slow motion. She was powerful, angry, vengeful, hateful, and at the same time loving, caring, empathetic and remorseful
I'm glad they portrayed a different story coz if they didnt, itd be one boring movie to watch.
And as for those who are upset for changing a classic story, Disney's classic stories are not original either. Read the Grimm's fairytale books. See how you like Sleeping Beauty there.
