"Get comfortable with people hating you," Sarah Treem, who created THE AFFAIR, which is in the midst of its third season on SHOWTIME, says about what it takes to be a boss. Her keen awareness about the messiness of real life is palpable in this epic series. Of course, it helps having actors like Dominic West , Maura Tierney, Joshua Jackson, and Ruth Wilson depict what the cost of prison, murder, infidelity, children, death, mental illness play on even the strongest relationships. This season continues to shed light on how people use, abuse, and find refuge in sex, lust, and love, but also delves into what it takes to live with baggage and the limits of resilience. Everyone and every relationship has a breaking point, and this season looks at what role mental illness, custody battles, prison, infidelity, children, death of parents, work play.
