I love crime drama to read and to watch. I've watched Line of Duty from day one and I think it's the best I've seen. The acting is great and the storylines are riveting. They keep you on your toes wondering and guessing who the villains are . My two daughters are keen followers too so as a family we have lots of discussions. I was so pleased that all the previous series were shown on the iPlayer so that I could refresh my memory before this one started.
