To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I have read reviews suggesting that this, the sixth series, is inferior to the earlier ones. I have to disagree. Indeed, I think this is perhaps the best of the lot. I add, in hope, 'so far'. The principals all give outstanding performances, as does Kelly MacDonald in the key guest role. There are implausibilities and unexplained elements in the story, as there are in earlier series, and highly complex forensic evidence is collected and analysed with such lightning speed our heads spin, but these plot indulgences aside, the story is compelling and the tension almost unbearable at times. Those who have followed the narrative from the start will want to know whether Hastings and his team get the 'fourth man'. They'll enjoy this watch, whether he does or not.
