I have to admit that the first episode (Part 1), was pretty great, except for the gruesome execution and the mysterious arrival of the underground train tracks. Once the tracks showed up, this production went entirely 'off the rails', as far as I am concerned. Episode 2 was so ludicrous as to be almost unwatchable. If this show had stuck to historical facts, passionate portrayals and authenticity, I would have given it 5 stars. Don't waste your time.
