I watched every episode of this expecting that at some point it would grip me in the way it has so many others. But I don't get it. I don't understand the high ratings. I loved Line of Duty, every episode of every season and I would happily watch it again, all of it, but I cannot accept a character, a Bodyguard, who hasn't the wit to put his mobile phone onto vibrate or turn the sound right down when it is ringing and ringing and irritating his boss, the Home Secretary, in the car. What did he say? Something like 'Sorry ma'am I have to keep it on for work.' I have a suggestion: one mobile phone for work and one for personal use. I didn't find the acting particularly wooden but the dialogue was rather unbelievable at times, the casting could have been better, and the plot? The plot was all over the place and we had every 'villain' thrown into the mix to throw us off the track of 'who dunnit' except for Russian gangsters. Or were there Russian gangsters and I just missed it among all the confusion.
