I tend not to watch TV – I just am not organised enough to tune it at the right time to catch things. What I do do is buy a complete run of a series and watch all the shows consecutively and exclusively. It has a weird immersive effect – after a while I even start dreaming it. Over the summer I watched the complete run of Battlestar Galactica -and have just finished it. I’m still not exactly sure what it all meant, but I can’t get it out of my head, so I guess it was good enough to make an impact. I’ve posted some thoughts about it to imdb here http://uk.imdb.com/title/tt0407362/board/thread/133739068?d=146411955&p=11#146411955 (Spoiler warning about the link though)
It’s probably the bleakest TV programme I’ve seen, but then it is about the almost complete destruction of all human life at least. I won’t say any more in case you haven’t seen it yet. I’d recommend it though.
