'Masters of Sex'
Human sexuality pioneers and real-life couple Dr. William Masters (Michael Sheen) and Virginia Johnson (Lizzy Caplan) fuel this critically acclaimed Showtime series about the research team who helped spark the sexual revolution of the '60s. In the vein of Mad Men, this premium-cable gem is stylishly nostalgic (right down to the well-coifed hair and seamed stockings) but really pivots on smart, sexy performances and nuanced, interlocking storylines. Most people have probably read more think pieces on Masters then have seen episodes of it, but while things definitely get steamy, it's not just a show about sex – love, jealousy, office politics and even familial obligations all come into play. The second season starts on July 13th, so get cracking.
