I think it ran itself out in two episodes
Saw the first two episodes. I think I get it.
Over time she'll actually descend into killing people herself. Then she'll have to find a way of getting away with it all so she can get her politically-correctly-casted son back. She'll descend into drugs and alcohol and waver between the low life and the high with what's-his-name. At some time just before the series ends, he'll get killed, she'll get away, she'll have lots of money stashed away, her mother will die of lung cancer and she and her son will be reunited. Yawwwwwwnnnnn.
Producers should stop watching other TV shows before accepting projects like this. The premise on how she and... and... you know, that hit man get together was interesting. But why he didn't just drive her into the woods and plug her in the back of the head will remain a mystery.
The first two episodes were just drama gimmicks, gimmicks, gimmicks. No thanks.
