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 analyzes reviews to verify trustworthiness.
I am not blaming Amazon but this was a nightmare. I ordered this for my very sick brother who lives on the west coast I live on the east coast, anyway this was the second DVD that was sent the 1st order had only 2 disks and he could not see the last 3 episodes, the DVD said there were 3 disks, I called Amazon and they sent another and did not charge me but it turned out that this DVD set only had 2 disks too. I ended buying the set from another store and it thankfully had all 3 disks. My brother is bed ridden and he cannot get out of his house and Amazon did try to fix this problem but it wasn't fixed. The woman I talked to on the phone wished by brother well and it brought me to tears, I thank her very much. Just a purchase that went so wrong.
