What TV show (past or present) do you think got off to a great start but then went the most off the rails? What would you have changed to keep the derailment from happening?
I suppose that Torchwood really changed too much over the last few seasons. I did enjoy the first two, but after the Children of Earth, it was all down hill.
I could say the same about Primeval, the seasons get shorter and they keep killing off characters or making them disappear. I would like to see the Danny Quinn and Patrick storyline come to a conclusion, the finale of season 4 really left that one hanging. Maybe Primeval: New World might have the answers.
