Some reviewers on here wouldn't know a good series if it slapped them on the face! This is a quality thriller all the way through that keeps you guessing and wraps it up with a decent ending. People say you have to pay close attention, surely if you are putting on a series or a film while doing the hoover or got your head stuck on Social Media on your phone then it's not worth watching, is complete trash and requires the attention span of a 3 year old.
Of course you need to pay attention to the detail and concentrate on it to be able to enjoy it and not get lost in the story this is telling. Pay attention as it actually requires some concentration on your part! As long as you do that, and stop looking at your phone at the same time for 5 seconds you might actually enjoy a good series for a change. Not going to give it away but it draws you in and doesn't let go till the very end. Brilliant!
