I have no idea what you tried to achieve with this animation. Albeit it features one of your most technically perfected animation, character designs and atmosphere, you mess it all up with a twisted ending à la M. Night Shyamalan. And by twisted ending I mean irrelevant, unforeseeable, absurd, ludicrous ending. But maybe it was the whole point since the beginning.
The mood you created is just about the tensest that's ever been felt in a horror-oriented flash movie on Newgrounds. The main character (though resembling Watchmen's Rorschach) is quite original and feels true, while, however, I'd say he's also a bit cliché, but then, isn't the whole story ? Wires cut, isolation, freezing north, big forest, a dog and insanity borderline ? It's so cliché that, once again, I feel like it's been planned to be.
So, I surmise it's not a movie about mocking furries after all, because it is so out of place and done over and over. It's more of a movie mocking horror movies with twisted, ridiculous endings. But what may confuse some people, is that it's a serious parody, crafted with care. It's not just a blatant exaggeration of typical horror movies aspects, like those spoof movies (Scary Movie, etc.) would be. It's a clever move, coming from a newgrounds animator, and it reminds me of that Ionesco's book, Rhinoceros, or the new Radiohead's album to a lesser extent. And in that aspect, this movie is great.
Or you could just have wanted to make a movie about mocking furries, in which case I'll revise my score to a lower one.
