What do i think? More than I can state here. Who is Cora? Harriet Tubman's name was not Cora. Watched only 3 episodes but think I am finished. Where are all of these trains coming from? In only 3 episodes I have seen 2 trains. I thought that only uneducated people thought that the underground railroad was a subway. If these trains are supposed to be a metaphor, it has been poorly executed. Very disappointing.
