What was the moral of this movie, exactly? It's clearly trying to portray money in a negative light, but the metaphor of money people is all over the place. So because people are money, spending money is bad...but the protagonist isn't spending money, they're investing it, and is getting back more money, so shouldn't that be a good thing? I was half-expecting the protagonist to be able to replace their ripped-off money-flesh with all the cash the investment earned, thus turning them into a giant super money-person. A story about money-people who get "spent" to death (including the ones we see in the alley near the end) doesn't make any sense when said people have apparently been making plenty of money.
Also, the money-people concept equates putting money into an investment to sacrificing pieces of your body to some kind of evil government/corporate entity...but it also unwittingly suggests that a person's identity and self-worth are synonymous to how much money they have. This is especially confusing because despite how the movie is dripping with an anti-money sentiment, it is accidentally very pro-money, and is giving the (rather poor) lesson that the purpose of money is for it to be hoarded. Something tells me this isn't what you were going for, and it muddles whatever message you were trying to convey.
And are you really trying to say that investing money is morally objectionable? Is that really the worst thing about money to dedicate a whole movie to? You could have made the movie about the evils of consumerism; or corporate greed; or wealth disparity; or the dangers of poor financial education--all while keeping the money-people concept. If you absolutely had to attack the concept of investing, maybe you could done a story about money put into bank & government loans getting used by the banks & governments for nefarious purposes, thus dooming investors to guilt by association. Even that's a bit of stretch, but I just have a hard time believing that something as tame as putting money into an investment is as bad as self-mutilation to appease a flesh-hungry corporate deity.
The 3/5 is for the animation & mood, which were done well, but the actual content of this movie just didn't sit right with me.
