This was a great series, highlighted by the amazing Morena Baccarin's portrayal of the ice queen alien, "Anna". It was far better than season one, and was oddly canceled by ABC, with a finale that is exhilerating but has no finale. You do not find out who wins/loses - and it leaves you stunned they would not think to spend the money on a 2 hour finale to conclude it (at least). The ending is much like reading a 20 chapter book, only to find the chapters 21-22 ripped from the book. If you don't mind this, buy it. I do, so unless another network picks it up (which is a possibility) and does more seasons and/or a finale/movie - I will not, it was an engaging waste of time as it is. It is a shame, as I would have given it at least 4-5 stars if it had a conclusion.
