The X Factor is one reality competition show that delivers that experience to its home audience also. At least on this show, when Paula's moved to tears, so are you.

The new episodes present an almost a too intricate meditation on power. Game of Thrones demands that you pay attention or be left behind.

We never know how fully such a mix might develop, and in this episode, it seemed undercooked by the end.

So much of the outright horror is recycled from films-The Shining, Don't Look Now, Poltergeist-but the plotting and pacing feel vaguely original, sometimes complicated and sometimes satirical, like American Beauty.

Unfortunately, the rest of the episode follows Dexter's descent into a routine guilt spiral, blaming himself for Rita's death (he should have "been there" to "protect her"), rather than ruminating on how it feels to be on this receiving end of a serial killing. How a series this smart could overlook the far more interesting angle is as much of a wasted opportunity as it is a disappointment.
