Howl's Moving Castle has been pretty good so far. I'm about three-quarters of the way through it and nothing has been exceedingly disappointing so far. I originally thought this was a YA novel, but by page one it was clear that it's more so MG. That isn't a problem. The style flows nice and reads fast, which I appreciate. Omnicient POV was appropriate here.
The characters are well-developed for MG. They could be deeper, although I think simple was a better choice in this case. Each character has a few defining features. None of the characters were dry or startlingly flat.
The settings are typically basic large-scale, with some intimated detail zoomed-in. That is the best approach for such a wide POV, in my opinion.
Anyone who likes whimsical fantasy may want to check it out. I give it about an 89% thus far, all things considered.
