first, let me say that i am not a fan of anime. maybe when i was first introduced to it, i was very much in love with the medium. but the more i saw, the more they seemed to be all the same. the novelty of sophicated animation for adults wore off. in the end, anime is essentially eye candy, leaving me with an empty feeling afterwards. i shouldn't only say anime, i'm not a big fan of animated movies in general. i wouldn't be caught dead going to see a disney animated picture. i will however occasionally dabble in some cgi movies, but i am always very suspicious of animation in whatever form.
so, metropolis had an uphill battle if it was to win me over. in the end, i was entertained, but i felt the story to be weak bordering on stupid (a lifelike robot girl who is the centerpiece of this weapon that can destroy the world). i didn't care much for the character animation, too cartoonish. however, i found the design of the world they lived in, this huge multilayered metropolis, to be pretty cool. the music was also kind of interesting, swinging 20's tunes, and occasionally the animation would have an old-fashion feel to them, especially the circular spotlight closing into a point transitions. i found a lot of similarity between this movie and akira though, and i didn't like akira that much either.
i don't consider it a spoiler, but in the end, a lot of things get destroyed, which is often the case with these japanese anime. the scenes of giant skyscapers toppling over made me feel queasy though, with all that's been going on recently. that stuff is serious now!
i wouldn't recommend this movie to anyone. i don't regret seeing it, it did hold my attention and if the story was boring, i could always admire the set design and the interesting futuristic architecture, of which there is a lot of in a movie called metropolis.
