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 don't subscribe to Foxtel due to it being owned by Rupert Murdoch. So I have invested in the BD 4K UHD format to be able to watch this excellent televisional feast. I highly recommend it both for the visuals, plot and the undercurrent messages about our society.
