The 1970s was the climax of sexual liberation, and middle-class families in suburban communities were ready to move under the tide of desire. It sounds really unexpected that the famous old man station actually filmed sexual liberation. The directors of this drama come from "Great Love" and "Rome". It seems not surprising that the bold style of HBO language has moved to the famous conservative CBS. CBS, which has been entangled in countless detective dramas and legal dramas for N years, put forward the slogan of doing something new and breaking through the old model this year. This drama is an action movie, which touches on the slightly sensitive topic of wife-swapping game in the 1970s. Can the controversial theme of open marriage and female consciousness give CBS some cutting-edge temperament? And how can sex experiments be shown on TV? Judging from the trailer, like the popular version of "Ice Storm", as for the stunt-full sex scene, there is almost no performance. But there are still many people who doubt whether this play is really suitable for CBS.
