I thought Cummings was a bit wishy washy which didn't help my viewing as his was the main character on which the film depends. However there were some good performances from Ann Sheridan (she glows) & old hands Rains and Coburn. The black & white helps.
A bit of an "Emperor's New Clothes" scenario. The screenplay, set designs and wardrobe are excellent but above all so is Catherine Frot in the title role – she gleams. Her supporting cast are fine but that is all they are as she is that good.
Very good and interesting overall although some of the technological terminology was a bit complicated for those of us who used a quill at school. Must be a "Deep Web 2" considering the miscarriage of justice.
The best bits are in the early panoramic water scenes before the humans get involved – when they do there is plenty of rattling of tin as the knights joust and fight.
