The animation is quite poor and it's very easy to spot the budget-saving moments of still backgrounds and stop animation scenes. The music is a lot more consistent though and I enjoyed the score for the first half. the sound in the second half is far more atmospheric.
In terms of character I thought the first half was very poor but the second half had some better characterization although it could have done with some stronger parallels with the first half.
Overall I'd say it's worth a watch if only for the brave move in storytelling but I suspect most will love/hate each half making it hard for people to fully enjoy the whole. While I was less than impressed by the first half, I can still see how it enhance the second half of the show.
