The performances and subject matter are pretty hard to criticise - Elle Fanning in particular is superb and is an eerily good likeness to the real Michelle Carter - the story is sadly compelling too. It occasionally dragged (despite the very sad and tragic nature of the real life story it depicted) so ideally it would have benefited from being a couple of episodes shorter. One main criticism I have though is that the text messaging was so frequent (plus an integral part of the story) that it should have been subtitled like the dialogue was. I had to keep stopping it to look closely at what was being said in the texts which was annoying!
