Doctor Who: Midnight - Rewatch Value

I've been re-watching some of the scarier episodes from seasons 1-4 of Doctor Who and it got me thinking that some of the best ones don't really have that much re-watch value. Blink is the biggest culprit. It was the best ever episode the first, even the second time I watched it, and I still enjoy watching it to a certain extent, but it is no longer really frightening. I already know what's going to happen and what the "twists" are and that ruins its effect. This is not the case for another episode, which I'll admit, I didn't quite appreciate before. I'm talking about Midnight. It's chilling and the effect of it doesn't wear off with each viewing like some of the other episodes. It doesn't matter that I know what's about to happen, that doesn't spoil it, because it's not scary because of the events and twists that occur, but because of the potentials, the unsaid things, the possibilities it explores. It's truly frightening because it seems that, finally, the Doctor has met his match. We see him scared. We see him fascinated by this new life form, but at the same time unable to understand it or to protect himself against it. We see how his arrogance in dealing with the humans on the shuttle has hurt him when they begin to suspect him of having engineered their predicament. It's brilliant. The capacity of human beings to be cruel, to hurt others in their fear, and the mystery of the strange new life form they meet are both chilling. Also, the acting. David Tennant and Lesley Sharp as Sky Silvestry both did an amazing job in this episode. You can almost say that Lesley Sharp's acting carried the episode. Without her, it would be not be anywhere near as frightening as it was. Her every movement, her little smiles, that glint in her eye, it was all so well done. At the same time, when she's playing the lonely, unsocial woman in the beginning of the episode you would never expect all of that. She just seemed like a normal passenger. In short, this episode is sheer brilliance and its frightening aspects don't wear off on second viewing. I would encourage everyone to watch it and watch it again! Although it is a stand-alone episode I wouldn't encourage you to watch it if you've never seen any episodes of Doctor Who before. This is simply because I think an essential part of the episode is the attachment the viewer holds for the Doctor. So watch some other episodes first, get acquainted with the Doctor, and then try this one! This is one episode where I can really say that Russel T. Davies excelled.
