However the series finale failed to strike a chord with many.
"Well... that was ... dreadful," tweeted BBC politics producer Darran Marshall.
"Fuming with the end of #Bloodlands the first 2 episodes were brilliant, the last 2 were such an anticlimax," Amy O'Connor wrote on Twitter.
Kirsty Hood added: "#Bloodlands - final episode. Hmmm..... Not satisfied with that conclusion. Too rushed as well."
"Well that’s four hours of my life I won’t get back #Bloodlands," Catrin Newman tweeted.
Many viewers questioned the show's continuity after Nesbitt was seen driving through the Mourne Mountains but the blizzard scenes viewers had observed moments earlier were suddenly nowhere to be seen.
