[5][6] Anne Lewis worked as assistant editor on the film, saying that it taught her how to "structure massive quantities of documentary material without the use of narration and about telling the truth even if it doesn't fit a popular notion of political reality.

"[11] Time Out criticised it, saying "Ophüls' partisanship is undisguised from very early on, but it's still difficult to forgive the way he loads the evidence […] the spokesmen for the British presence and some of the more bigoted Protestants are sufficiently eloquent in condemning themselves without interference from Ophüls' self-satisfied liberal smugness.

"[12] John O'Flynn's Music, the Moving Image and Ireland, 1897–2017, noted the opening scene, which intercuts shots from the New York City St. Patrick's Day Parade with shots from republican funerals, as an implied criticism of NORAID's financial support for the IRA.
