This play, and almost all the words, were from Thomas Middleton's 1606 play. A much better description than Netflix's packet is:
From Denver Public Library site: Timeless themes of moral corruption and revenge are played out on a stage of gritty, punk futurism and anarchic violence.In a post-apocalyptic Liverpool of the future, a wronged man returns from a self-imposed exile to bring down those responsible for his wife's murder. Contains strong language, violence and sex.
The Netflix packet said it was a "futurist sci-fi drama" and it really wasn't SF. The latest thing in the movie was a cellphone of the type that needs to be holstered. I think what made them write "sci-fi" was the punk style. It's set in 2011, and we aren't quite that punk, but we aren't post-apocalyptic, either. There was a lot of blood, but really good acting. Christopher Eccleston is the protagonist, coming back to get revenge because the Duke killed his wife, and the revenge doesn't go quite how he expected.
I really liked this.
