I am actually planning to go back and watch BtVS again ... starting season 3 ... yes, I said 3, as I have a couple of WIPs I want to get done - but this time I shall keep going.
I also want to re-watch Blakes 7 ... I watched it a lot some years ago, so it will be good to get through those 52 episodes again.
I ahve also just started watching Life On Mars -
Sam gets sent back to 1973, from 2006. A popular series that I somehow missed. I've seen season 1 now, and want to start #2 soon.
