The story really deeply affected me, and I think it was an amazingly effective use of the medium. I can't really think of any other way that it could have been presented in any medium that would have established our concern for Alison (by "being" her parents, the kid with a crush on her, Wendy). It's agonizing to realize what's going to happen, and to be powerless to do anything about it.
The final act of turning off the light is so, so sad.
