What Do You Think It Was?

I don't think that they ever really settled on what it was. And, and I think that it's better that we don't know. In the show, there are clues, they say it was very cold. They say it defied gravity. There's a bit in the episode where Nessa gives birth where Bryn is stood by a vending machine with cup of soup. If you could present any other show on TV, what kind of show would you choose?
