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 ordered this Box Set in January 2015, but did not play it until yesterday 10.6.2015 because I had accidentally put it with DVD's I had already seen. Only one episode of the first series would play, and none at all of the second series - all of the discs came up with 'no read'. I have two DVD players and neither of them could play it, so there is nothing wrong with my DVD players. It was very disappointing - a complete waste of money. Although it isn't my fault in any way I am now too late to ask for a refund or new set of discs. I am very annoyed - this was not a cheap purchase and it isn't what I expect from Amazon. There must be other people with this problem, SO BE CAREFUL IF YOU ORDER THIS DISC, and if you really want to buy it, make sure that you play it within the time allowed for refund.
