Without repeating the general setup of the story, the series is centered around Watt's character Jean. To say that she's complicated is a vast understatement. The episodes leave enormous unanswered questions about what is driving her tremendously aberrant behavior. That will either frustrate you terribly, or leave you intrigued as I was. The final episode leaves many loose threads in the plot line so I assume it's a cliffhanger, though one could possibly read the ending as a hanging question grand finale. If you can hang with a sometimes low- energy plot, if you like watching a great actress testing her limits with a totally out-of-the-box character, you may enjoy watching Watts as Jean. She is one twisted sister, that I can promise you.
