This show is fantastic, from the writing through to the acting. Some others have framed it as a psychological thrillar about social media but really it is about friendship set in the current day. It is also has a pheonominal character depth, especially for the female characters. It's writing is complex and compelling, so much so that you at risk of binging all 6 episodes in one sitting. This show brings something different to this genre. Something which is important. This will win baftas. The ending is also perfect. If you are looking for a show of depth and emotionally complexity and you have empathy, this is the show for you.
