Is this series finished? Hard to tell from the last episode but it does wrap up the main story line.
There's a good, slow reveal mystery here based around flashbacks to a time in the United States in the 1980's not covered much these days. It also revolves around abusive and manipulative men psychologically tormenting women much like your average Lifetime movie but it's better than one of those.
The main problem with this series is that the character we follow isn't the tormented personality played by Toni Collette but her daughter as we follow her frantic path of discovery about her mom's mysterious past. Unfortunately the daughter isn't given enough sympathetic characteristics to elevate her above a 30 year old screw-up. She's initially portrayed as helpless but suddenly becomes a pro at evading professional security goons out to get her. Since, unlike all the other main characters, we are given almost nothing about her (except that she's a drawing artist), it's very hard to follow and care. And the other characters are for the most part flawed people.
