I agree that the spectacle and action sequences were definitely the high light of 9 and that the story narrative was lacking. The characterization was flat and the narrative just could have been more. The world that the director/writer had created definitely had potential to become a very nice epic storyline, but it didn't. I feel that the director wanted to push it, but hesitated because he felt it wouldn't attract kids. He should have just gone all the way and pushed the envelope, but oh, well. I'll probably get it on DVD just cause I enjoyed it and it's something I can see myself reliving, if only for the visuals, music, and fight choreography. However, I'm not sure why people found the ending confusing. He reverses the polarity of the device using it to suck out his friends' souls thus rendering the Brain without energy. And then released the souls later on so that they could merge once more (being the doctor's soul split into separate individuals) and ascend to heaven, or whatever. Granted that's an obvious summary of what everyone saw, but I thought it made sense. It seems that the professor was a bit of an occultist and melded technology with sorcery or alchemy. Granted, it doesn't really explain why the hell he built a mystic talisman into the exterior console of his big Brain machine, but, whatever. Apparently he did and it back fired. It's not a perfect movie, but it sufficed for me (though I'd still take WALL-E and UP over 9 any day).
