Impressive set designs and trappings. Although long it is never boring because it basically respects the historical truth of a fascinating period. Michael Jayston does very well - the supporting cast oozes British acting talent.
The casting is spot on. Jarvis is in every scene and does remarkably well for a young 'un. She has a great head butt.The dialogue is concise and in your face.The scene with the kid in the river looked authentic. The dance number with mum and the two sisters reminded me of "Bande a Part"(1964).
Big budget film makers eat your hearts out.
