my biggest gripe is that it needs to be more vibrant. every movie made these days falls into this issue, it seems, so it's hardly a critique exclusive to wicked. for a world as fantastical as oz, it is lacking in color and vibrance. yes I saw chu's response to this, but I'm not sure I buy it.
I have plenty good things to say about it, some bad, but overall I'm pleased! it was fun, and I think it's enjoyable for new fans and old.
