Okay so tonight's just terrified me

I'm not one for torture and violence (I know there wasn't much but the threats were enough) and was about to switch off when the big twist came, and I stuck with it to see how it'd pan out. And what an outstandingly clever idea. A great episode, terrifying but very well written once again. I salute Charlie Brooker.
The irony though of some on Twitter suggesting that's what needs to happen to child killers is totally lost on them. Missing the point in a spectacularly ironic fashion.
The girl was a fantastic actor as well. Those screams were haunting.
