I opted to see the regular version of the movie and not watch it in 3D. I’m not a fan of the “cram as many special effects into every frame as possible” movie variety that seems to be so popular nowadays. This movie was pretty much that anyway even without the 3D. It was a fun movie though in spite of all the high tech "cinemagic".
The setting is 20 years before the Judy Garland Wizard of Oz move we all know and love. Prequels are all the rage now you know. It tells the story of how the Wizard got to the Emerald City and became the great and powerful OZ.
