Inevitably there are scenes and connections from the book which are missing, the story has been compressed to fit into a 2hr film, but it is visually and feels very like my imagination when I read the book. Since I greatly enjoyed the book this is high praise. Ultimately it comes down to a courtroom drama, which is well told and the jumping between time frames in the novel is handled well.

The visuals are excellent and Daisy Edgar-Jones is very good as Kya (although perhaps a bit old for the teenage scenes). Jojo Regina who plays 7yo Kya is also very good.

I can't comment as to whether it works well if you haven't read the book, but if you have you wont be disappointed.
