I think the real meat of "Hansel and Gretel" is the perfidy of the father and stepmother, and that whole aspect somehow got dropped here. The emphasis on inner beauty and self-sacrifice seems more like the theme of "Beauty and the Beast" than "Hansel and Gretel." I feel like we danced toward it now and then, with the reference to the soldiers' sickness, but then we veered away from that sort of "sins of the father" motif and went back to altruism and love-despite-appearances.
It was fun, and I enjoyed it. I wouldn't give it full marks, though, as it just didn't seem to ever hit its stride. Others have suggested it didn't bring enough creativity to the retelling; I think the muddling of the themes might have more to do with it, and I'm sure others have their own biases and preferred modes of interpretation. Somehow, though, it didn't seem to get all the way there. A hint of a limp. A slightly off-key note.
