I broke up with Torchwood in the middle of Children of Earth. It wasn't even the big thing that all the fans got upset about, it was that I got spoiled for the end and realised it wasn't going to get any better--watching it was like torture, and I'd been holding out for if not a happy ending at least a hopeful and satisfying one, and realising that wasn't coming I just couldn't summon up any more interest.
