I searched but couldn't find a thread ... it's an eight-part Rich People and Their Secrets drama about the murder of a Manhattan businessman who was married to two sisters consecutively.
Jessica Biel is very good as successful uptight wife #2; Elizabeth Banks not so much as #1 (we are asked to believe she was addicted to drugs and alcohol for decades). Kim Dickens is big fun as a Southern lesbian police detective in New York, and her partner looks like a cross between a young Sacha Baron Cohen and a 1970s porn star. Matthew Modine is in the mix as an elderly gay lawyer.
Not the best thing ever put on film but infinitely better than "Sirens."
