The previews were, overwhelmingly, for dystopian coming attractions -- surprising for such a kid-oriented film.
The opening titles are really beautiful! Based on antique card advertising with a little nod to classic circus and vaudeville billboards, they feature engraving-style graphics and antique typography, seemingly held before the camera with marionette rods. There are some nice bits such as the small, traveling "Baum Brothers Circus" venue for stage magician/fraud Oz. There's a bit about one of the girls he saw when in town on the circuit stopping by to announce her decision to marry local farmer John Gale. It's an entire scene, but not too heavy handed and, appropriately, never referenced again.
I wouldn't class this as a great film but I enjoyed it. I felt the production team did a nice job of creating a back story to the classic which hit all the right homage and style notes, and set the stage for the story to come. At the same time they presented a stand-alone story from some of the lesser known books and made good use of current technology to enhance their own vision. I recommend it.
I will honor Monkey in my heart, and try to keep it all the year.
