I really like the show but I think the restriction of doing the show in the past limits the impact this news broadcast can have.
What is kind of disappointing is that their method of only providing news and the best argument from each side is that it can never change the landscape of how television news is done in the shows world because the future is pre-determined. In order to change they would have to break with the assumption that the show is set in our recent past and that the future of the show will follow the same trajectory as our past. On the plus side they gain the ability to re-tell the news from a different perspective which is interesting. But this keeps the world the show is in very small almost limited to the newsroom itself.
