Critics Consensus

Masters of Sex closes the book with a stylish final season that doesn't aim to scale the heights of the series' artistic peak, but satisfies with its thoughtful investigation of its two protagonists' diverging paths.

"Masters of Sex" may never get to the bottom of our questions, but it's back to enjoying itself trying to figure them out. So will viewers, if they can give these star-crossed lovers another chance.

Jan 16, 2019 | Full Review…

It... strongly suggested that the Showtime drama was, following that wobbly third season, once again on solid footing.

Sep 12, 2016 | Full Review…

Showtime's Masters of Sex is daring, surprising, and often beautiful, owing much to its stellar cast and writers.

Aug 30, 2018 | Rating: 7/10 | Full Review…

A satisfying fourth season. [Full Review in Spanish]

Jul 10, 2018 | Full Review…

Any opportunity to see more characters significantly expand the Masters of Sex world sounds good to me. I'm planning to keep watching, but the show's definitely been given a warning.

Sep 14, 2016 | Rating: 7.5/10 | Full Review…

If Masters of Sex keeps going on like this, it's going to dissolve into a bad spoof. Good luck.

Sep 12, 2016 | Full Review…

With Sheen and Caplan, and the amount of historical material still to cover, I'm hopeful that Masters of Sex can at least be more watchable again, even if it doesn't return to the creative heights of that first season.

Sep 12, 2016 | Full Review…

Maybe Season 4 will get better overnight, but based on the early sampling, Masters of Sex feels like a show that would have been better had it wrapped up the story concisely, as a limited series.

Sep 12, 2016 | Full Review…

Masters of Sex Season 4 is one-half return to form, the other half a full-hearted experiment to breathe new life into the series that is sure to satisfy longtime viewers.
