I liked it fine. I'm surprised how many people are reading way more into it than I did (and than I think the author intended them to). What I took from it was that everything, not just video, is malleable, not because the story took place in some crazy science fiction world, but because that's how it is, and has been. The sfnal elements in the story highlighted the fact that our culture is moving further in that direction, and becoming more accustomed to it as technology makes the apparent line between the real and the fictional more and more blurry.
I'm not sure how well supported this is by the story, or if the author would agree, but my own take on it is that this blurrification, rather than indicating that it has in fact gotten easier to move between fiction and reality, indicates only that now we're more aware of it, since we are losing are (always false) perception of media as authoritative. Certainly it is becoming easier for anyone to deceive the gullible, but the numbers of the gullible are shrinking as those same techniques that enable deception become available to (or enter the consciousnesses of) those who used to be gullible. So rather than chilling, I found this story to just be a pretty well-done and fun bit of insight into an important fact of modern society, one that can and will be used over and over for both good and evil.
