The two-part drama received some positive reviews in the UK, especially for the script and acting, although
The Guardian described it as "pallid as much of the washed-out photography". The
Telegraph liked the series for many features: appropriateness for "intergenerational shared viewing, never... too visually brutal, and the playing of the minor characters... was convincingly understated". The
Guardian complained: "It should have been the perfect spy thriller. It had everything. Except tension". The
New York Times found the series an "enjoyable, straightforward espionage tale without a lot of twists or extra layers" but deemed it "true to the original in story and in spirit", and the
Boston Globe thought it "a strangely bloodless affair". Rotten Tomatoes rated the television series 64% from critics and 50% from average audience. ==References==
