I will be honest, with names like James Nesbitt, Sarah Parish, Eddie Izzard and Cush Jumbo in the cast this was always going to be a show that I would be watching from start to finish.
The first episodes were a bit messy, but after that it had me hooked and I binged it in one sitting.
Some would say it was convoluted and they would be right, it has lots of twists and a few red herrings, but you have to persevere with shows like this if you want to be entertained.
The one star reviewers who didn't even get through the first episode deserve to miss out, if you have the attention span of a gnat, you deserve to miss out. Go and watch a show with lots of explosions.
This is not what I would call a brilliant show, but it has a lot of twists and they keep coming right to the very end and I mean that literally.
If you think you should give up after the first episode or during the first episode, don't this is worth the 7+ hours required to watch it.
Not sure I would watch it a second time, but it is likely if given enough time between viewings.
Easy 7/10 for me.
