We live close to Quarry Bank Mill, saw the filming but missed the series. I am about to purchase on DVD for ourselves but potentially for my 9 year old daughter who loves history with a particular interest in the Victorian era. The DVD states a 12 but the blurb says 15?? I know the content will be dark but just deciding whether she could deal with it or not given the historical content. Will prob watch first but any thoughts would be welcome.
