I just caught the first and second episodes of this. Will watch the third one on Friday when it's on ITV.
Fun Fact, this was filmed in my home county, here in Ireland (Wicklow) - It's supposed to be based in the UK but it's all here. I remember last year I was driving home from work and there were all these British Road Signs on the N11. I was like, eh what the feck...then I found out they were filming this. All of the seafront shots are from the Bray Promenade, which is about 15 minute drive from where I live. Oh and it's the home town of Olympic Boxing Gold Medalist, Katie Taylor.
