[3] The series follows the lives of people growing up in Belfast in the 1970s, 1980s and 1990s during the Troubles, as well as their involvement in the Provisional Irish Republican Army, and inquiries into the Disappeared and particularly the murder of Jean McConville.

[4] Interviews from the Belfast Project are woven into the narrative which also includes depictions of the 1973 Old Bailey bombing and the subsequent hunger strike by the Price sisters, Dolours and Marian.

[7] In February 2024, Lola Petticrew, Hazel Doupe, Anthony Boyle, Josh Finan and Maxine Peake were confirmed as the lead cast.

[8] The cast also includes Michael Colgan, Kerri Quinn, Stuart Graham, Laura Donnelly, Rory Kinnear, Amy Molloy, Helen Behan, Damien Molony and Judith Roddy.

[24] Benji Wilson of The Daily Telegraph gave Say Nothing a grade of five out of five, describing it as a powerful blend of history, tragedy, and thriller, effectively weaving together multiple narratives that span four decades of the Troubles in Northern Ireland.

He praised the series for its compelling portrayal of key figures like Gerry Adams, Jean McConville, Dolours Price, and Brendan Hughes, noting their strong performances and well-developed storylines.

[9] Lucy Mangan of The Guardian rated Say Nothing three out of five, saying it could have easily become chaotic, given its multiple narratives and time shifts, but it maintains clarity by firmly grounding its characters and their stories in history.

She noted that while the series is emotionally engaging, it sometimes feels overly sympathetic to its main characters, particularly the Price sisters, Gerry Adams, and Brendan Hughes, and fails to fully address the consequences of their actions.
