Perhaps my favorite aspect of "Tokyo Godfathers" is that it isn't what you might expect from an anime--really, from an animated movie of any kind. In its own way it serves to prove that a simple, no-magic and no-monsters modern-life story can be told effectively through animation. The way in which it fell short for me was in the fact that it seems to rely too heavily upon being -endearing- to the viewer. In other words, I felt like throughout the entire movie I was supposed to be saying, "Awwww, how sweet / cute / bittersweet."
My problem was that I didn't really find everything to be quite as "endearing" as it was meant to be. When Gin joked about eating a family of cats to quell his hunger, the cats crowded around Miyuki and hissed at him. Instead of thinking, "Awww, you better leave those cute kitties alone!" I thought, "Wait, cats can understand Japanese??" In the case of Hana's character, I felt like I was supposed to be saying, "Awww, he's such a sweet transvestite, poor thing." But I guess I never considered the fact that he's a gay transvestite to be reason enough to objectify him as some kind of giant teddy bear. Additionally, I felt like there were an awful lot of convenient (or inconvenient) coincidences going on...maybe it was all just part of a "Christmas miracle."
Anyway I will say that it's been a while since I've seen a slow and thoughtful Christmas tale aimed at slow and thoughtful adults like me, so I'm certainly glad I watched this film. I'm also glad it didn't follow the formula of "psychadelic split-personality girl" that other Satoshi Kon movies seem to be following (although don't get me wrong, I loved Paprika). All things considered, "Tokyo Godfathers" is a light-hearted film, and maybe that's why I had trouble with it. But in the hopes that you're more capable than I am at getting into the spirit of a light-hearted film, I'd say you should take a look.
P.S. I loved Hana's haikus!
