Slow Horses Returns With Its Best Season Yet, Review Says
Slow Horses is a spy show about agents who are not treated as the best spies.
In its sixth season, they face dangerous killers and a fast-moving crisis.
A new lead writer took over, but the reviewer says the show is still just as good.
Gary Oldman returns as Jackson Lamb, and Kristin Scott Smith plays Diana Taverner.
Taverner is pressured by a television network owner and becomes involved in risky choices.
The season mixes jokes with frightening action.
The reviewer says it is the best season yet and gives it four stars.
The review calls season six the strongest installment of the spy thriller so far.
Gaby Chiappe takes over as lead writer from series creator Will Smith, but the reviewer says the change has not harmed the show.
The six-episode season sends Slough House agents into a fast-paced hunt involving Russian killers Jane and Jim.
Gary Oldman’s Jackson Lamb and Kristin Scott Smith’s Diana Taverner remain central as Taverner faces pressure from TV-network owner Cantor.
The review praises the balance of comedy and suspense, gives the season four stars, and recommends watching without delay.
