There is a freshness to the casting - not the usual stars toting machine guns. The screenplay is well-written.
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.
