Took DW, DD2, and DS2 to go see this the other day. Fantastic movie! ! !
The first 5 minutes are a bit hookie, but after that it gets really good really fast. Not for real young kids, there are some pretty dark parts and some graphic violence, but it is required for the story line.
It is a whole other take on the story and quite frankly a much better take. Angelina Jolie IS Maleficent, right down to the slightest gesture and smile.
I did figure out the twist before the end, but not all the details.
I will not say more other then go see it. We saw the 2d version and there are a couple of scenes where it is obvious this was shot for 3d, but all in all it was awesome!
