Overall I felt this was an excellent movie. It felt very true to the original Wizard of Oz in style, but with updated graphics and special effects on par with Avatar. The scenes were vibrant, the colors rich, and the acting well-done.
The only negative is that the opening intro (all in black and white) seemed a bit long. Although, to be fair, I'm not certain how it could have been condensed, just that that part felt a bit slow and tedious. The rest of the movie was amazing and a must-see for Oz fans everywhere.
