True, Vicky McClure is talented and she has had several pleasant roles and performances in thriller series (e.g. Line of Duty, Broadchurch), but in a teamwork - as modern sophisticated crimes are not solved by a single individual any more.
Well, Lana Washington is part of a team as well, even a leader, but the camera is too much on her and even her co-workers are some gophers around that you hardly remember their faces... The plot has its twists, but the outcome is often airy-fairy - as even laymen know how widespread and thorough are nowadays security (background) checks. The creators have evidently also thought that dedicating many minutes for defusing a bomb is thrilling to most of viewers - in fact, it is rather boring and protracting as it is unlikely that the leading character gets killed...
In general, Trigger Point is more than average, but not much - for a British series.
