Viewers finally got (some) answers as to the identity of the murderer known as Goliath. After the drama alluded that James Nesbitt's character, DI Tom Brannick, was the true killer in episode two, episode four seemingly confirmed that the detective was the culprit. However, it wasn't that straightforward.

The detective revealed that he had been keeping the killings under wraps for 20 years, but only because the real criminal, David Corry, had blackmailed him to do so after threatening to harm his wife.
The revelation left many wondering whether he is the true assassin, and why he was now admitting to the murders. Could there be another killer out there, and is Tom being framed?
Taking to social media, one person reacted to the unanswered questions, writing: "I'm glad there's a second series of #Bloodlands. More holes in the ending than a Mint Aero!" A second person said: "I honestly do not know if I loved it, hated it or it totally confused me. Bring on the 2nd series. I think! But I'm not sure... #Bloodlands #confused."

A third echoed this, writing: "I saw there was a series two and thought, he can't be guilty AND get a second series? #Bloodlands." Many will be pleased to learn that more episodes are on the horizon after BBC confirmed that series two was definitely happening at the end of the finale.
Leading star James discussed reprising his role in the future, stating: "I'm thrilled that viewers responded to Bloodlands so positively and that we will be returning for a second series. I'm always happy to be back in Northern Ireland and to reveal even more about Tom Brannick."
