Why so much hype?

Powerful

Excellent adaptation.

It is an exhilarating, distressing, funny and profound film, with one of the more memorable film scores in years,

From the trailers this looked like a dark tale of revenge and torment, after the opening few minutes it seemed like that's what was on the menu, but sadly the quality of the opening quickly fell away, and it became repetetive and pretty dull. It felt a little like an attempt at a Black Mirror style story, just lacking the quality ingredient, Charlie Brooker. Praise for Nick Blood and Faye Marsay, they did their best with the weak script, both characters had stuff to do, but the others seemed like extras, serving zero point being there. Channel Four has a good track record with revenge dramas, thinking The Watchman and Cyberbully, both were gripping, this one was so flat in comparison. More plot holes then you can dream of, how did she find them? How did she get their passwords? How did she get them there with nobody seeing her? A great start, good premise, just ultimately lacking.
