As is usually the case, I found 2nd person a distraction. I can see where Fenrix is coming from on it being appropriate for the reversal. But... since I am not a woman, and I am not afraid of mirrors, the story telling me these things makes a dissonance throughout.
But, despite the 2nd person, I quite liked it. Mirrors moving out of synch with you is a subtle and scary element, not the first time I've seen it (i.e. Season 1 of Heroes, though I think it was metaphorical there)--especially seeing your closed eyes in the mirror the moment after blinking. It all added up to a sense of the creeping inevitable. We as the audience know that there is something to fear in the mirrors, because we're listening to a horror podcast and the episode is focusing on mirrors, but when you know you must be afraid of nothing because the alternative is that there is something horrible coming for you and you can't quite face that in the light of day, then it has all the time in the world to make its move.
