The resemblance to Alice stops at the journey to an alternate, if mysteriously connected, world; instead, "Wonderland" is an uneven mash-up of different Miyazaki films which is somehow more than the sum of its parts. The characterization is wanting: the Alchemist or his sidekick are uninteresting rather than mysterious, nor do we know much about their powers, let alone their personas. And who is this sleepy wizard at the end? All that aside, the portrayal of the landscape is beautiful, and the idea of having an insecure but kind-hearted (high schooler) learn about herself while being shepherded by an aunt who annoys her (and the viewer) somehow works, as she gradually opens up to adventures and connecting with people. The movie has numerous Miyazakian themes, from its steam-punk setting to the environmental theme (water is becoming scarce), but, most of all, it reminded us of one of the lesser known works in that canon: The Cat Returns, with which it also shares a very similar animation style.
My kids both really enjoyed Wonderland. They were in the mood for a Japanese movie that was better (and easier to follow) than Children of the Sea, and this gave them something strange but familiar.
