Like many of the fairy tales we heard as youngsters, Disney’s Maleficent contains some plot elements that are head-scratchers.

We meet the young Maleficent (Isobelle Molloy) when she’s an innocent girl fairy, living an idyllic life of flapping her wings and flying around an apparent paradise. She shares this happy universe with a number of creatures that look like refugees from Lord of the Rings and Harry Potter movies.

She forms a friendship with a human from the neighboring land of kings and queens, young Stefan (Michael Higgins). As they grow into teenagers, they continue as chums. But when they become adults, Maleficent (Angelina Jolie with cheeks sharp enough to slice bread) and Stefan (Sharlto Copley, who we met in District 9) see their relationship take a strange turn.

The dictionary definition of maleficent (“doing evil or harm; harmfully malicious”) gives a clue that things may not always continue to be goodness and light for her.

The king of Stefan’s home kingdom leads an ill-fated invasion of the fairyland and his guys are turned back thanks to Maleficent’s power. The king declares that whoever gets Maleficent’s wings will be king when he dies. Stefan, her old friend, sneaks in and manages to do the dirty deed and gains power while Maleficent loses some, but not all, of hers.

She places a curse on Stefan’s daughter Aurora (the remarkably cute Elle Fanning) that dooms her to go to sleep at age 16 and not be awakened until she gets a kiss that comes from true love. Aurora is raised in the woods by 3 fairies, characters that should be charming and memorable, but somehow lack those qualities.

Maleficent is always hovering nearby, monitoring the child’s growth. She has her sidekick Diavil (Sam Riley) alongside, turning him into whatever creature she fancies. He could pass for Orlando Bloom’s less good-looking younger brother.

Eventually, most of the characters live happily and others get by as they can. As mentioned, some of the things that happen are head-scratchers. For instance, just when we think we have Maleficent figured out, she changes her mind—like with that curse thing.

Maleficent is a good-not-great movie, with many wonderful and amazing images. Director Robert Stromberg’s lengthy movie resume is mainly as an effects guy. He does an excellent job of mixing live action by human actors with computer-generated effects.

But the big question remains: Is this movie too scary for little kids? I say yes. As an overprotective dad, I might’ve rated Maleficent PG-13. But it has been deemed PG. This ensures that a good number of little kids will have nightmares. Thank the MPAA, mom and dad.
