Borrowed a copy from a friend, glad that's the level of financial support I'm offering for it.
I did not enjoy the movie. About ten minutes in I started yelling at the screen level not enjoy.
My issues (YMMV):
1) James Franco. His "Oz" never seemed a part of any of the worlds he was set in. His mannerisms, accent, mode of speech all were part of a very modern character. I never once believed he was anything other than an actor who was - very visibly - happy to be there.
2) CGI. I found far too many moments where I was more involved in how little on the screen actually existed, and comparing it unfavorably with Sky Captain and the World of Tomorrow. How often the actors were not *quite* watching or interacting with the CGI characters. How frequently the lighting would be flat when characters were walking in bright sunshine, or the shadows would be sharp and offset (and rather amorphous) when in indirect lighting - all stuff that should have been solved a decade ago. Very frequently I found myself intensely aware that I was watching an actor or two performing on a soundstage with no actual set to work off of.
3) Women in the movie. Or, the real lack of them as characters. Sorry, just the way it looked to me.
4) Predictability. Not just in the "we know where this is going" sort of way. How many ways can you repeatedly stress "that poor girl" before you are forced to accept that "that poor girl" is going to become a major player in a bad way? It wasn't foreshadowed, it was printed on the side of a six mile long zeppelin and flown through the screen.
5) Enough with the 1950's style "we did this just for 3D!" crap. I expected it out of Roger Corman, not Walt Disney. SO many shots were blatantly put in just for that 3D zinger. It was beyond distracting.
If you legitimately enjoyed the movie, more power to you - you saw something that I could not.
