Besides superhero movies, the latest trend seems to be fairy tale retelling. Maleficent tells the story of Sleeping Beauty from the evil fairy's perspective. Even just reading that, it's obvious that she's not as evil here as she was in the original story.
I like these sorts of retellings. The "evil" characters become three dimensional, instead of just the two dimensions that we used to get. Most of the time in real life people have their reasons for doing what they do. Also, sometimes the real villain is not the one you would first pick out to be. Without spoiling too much, I liked her reasons for doing what she did, and I also liked the way they resolved it.
