Torchwood 2x05 (no spoilers)
Can't be bothered to write about it properly - I've exhausted myself fangirling all day (I watched Cloverfield earlier. Now that is a damn good film).
But it was definitely the best episode Torchwood have ever done and I loved it. I wanted to shrink Owen down and keep him in my pocket.
I'm just sad that such a brilliant episode will inevitably be eclipsed by next week's, which was shown right after it on another channel. (I didn't watch, but I know full well what happens).
