I like my story metaphors subtle, lurking on the edge of vision as I watch the story, glimpsed only if I turn my head very quickly then gone again until I stop looking for them--they can be lured out with earnest forum discussion, and sometimes by cookies, but otherwise they stay out of the way. I don't much care for metaphors that can't be ignored, levelling city blocks just to get my attention, and being so much bigger and stompier* than the story itself that I don't even notice the story anymore. And then suddenly the metaphor ends, and I'm left wondering what the hell happened to the story while I was watching the all-consuming metaphor.
*I believe this is the only time I've ever used the word "stompier", but certainly not the last.
Anyway, the human story was interesting, and the cancer-monster metaphor was interesting but it was just too stompy for my tastes. And in any case, why the heck does this one random human with cancer have such an apparently profound connection with a monster on the east coast that's nowhere near this person? At least the Kaiju Storm story had a slight explanation, if a flimsy one, that he'd met another monster and somehow forged a connection. To me that makes the whole connection into nothing more than a literary device, one that I have trouble looking past. I mean, of course metaphor is a literary device, but if I can't avoid seeing it as anything but that, then it didn't work.
And because the metaphor was such a beat-you-over-the-head variety, it's hard to not overextend it. So his mother was like America, yes? With the cities as organs, the monster as cancer ravaging those organs, and the military being medical science trying to pound the monster into submission. But the metaphor stops working when the mother dies, and then many monsters appear. If you follow the original metaphor, then her dead body is now ravaged by cancer? Huh? Or is his mother merely the Eastern Seaboard, and he himself is America, but then somehow he contains his mother? Or is it just a bad case of mixed and mangled metaphors?
Regarding the televization of sports games. At the very least, it would make for a very different betting dynamic. Imagine the winners brackets, but all the ones in the northeastern seaboard are crossed out. "I really think Atlanta will win it, but only if the monster doesn't smush Atlanta before the Finals." So they'd still have to pay attention to the monster, if only to predict which cities will lose their stadiums and teams due to monster rampages.
Also, I had trouble with the ending. It's great that his wife is there for him, and is willing to support him--she's a keeper, and I hope they're very happy together, or as happy as they can be. But, when he says "you're welcome" to her, it seems to me that instead of using her support to help him carry through the tragedy, he's using his wife as an analog for his mother, trying to replace one with the other. That doesn't strike me as healthy behavior.
