The visual design was great as always Tarsem's, with a hint of the late Eiko Ishioka touches in it. It's almost crime to waste such beautiful designs to such a mess of writings. It's so many plots, yet so many holes and so little of story in it. In mid-series, it actually was getting better, but then just to crumble again into unsalvageable mess until the end.
The overall idea is pretty cool considering that I really don't like the original Wizard of Oz book, maybe I'd enjoy this inspired one. The costumes and scenarios are beautiful as always in a Tarsem project but OMG... the casting! Not a single one of the actors involved made me engaged. Maybe Jack a little when he got axe rage and everything... but that's it. Everyone looked kind of bored. I'm bored.
