n my opinion it was a great movie with some interesting elements, even though having some plot holes and the ending probably was just too messy and crammed together, but still fun to watch and not your casual movie that is similar to all other ones.

A film with more than the usual spoiler issues. Talking about it in any detail feels akin to handing you a gift-wrapped present and saying, "I hope you like it -- It's a thriller about a diabolical secret experiment."

While it doesn't offer any answers, it both thrills and makes you think.

Through painfully honest and emotional moments, the movie becomes irresistibly relatable

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.
