This is Charles Dickens' Oliver Twist reimagined, 176 years after the original was published. It is gritty and urban, dark and (forgive me) twisted. When you consider the themes and storyline of the original Dickens novel, that was also very much the same for its time. But I suggest you don't compare the two books, that you come fresh to Twist, with no expectations (as opposed to 'great expectations'). Because really, it deserves to stand on its own.
We meet Oliver Twist as an 18-year old orphan with a rap sheet, eluding police. He's an incredible graffiti artist who may be as good as, maybe better than, Banksy; able to memorize and reproduce the great masters with an incredible eye and meticulous detail. He comes to the attention of FBoss (Fagin), when it appears the thuggish Sikes and Red (Nancy) have gotten into deadly trouble with the Russian mafia about - what else - some paintings. They need Twist, but he doesn't need them. Not until he starts to fall for Red...
This is an unsettling walk through London's underbelly, exposing a seam of crime most people never dream about. It's very visual, so I imagine the film - the screenplay appears to have been written(?) - will be terrific to watch. Especially the chase scenes where Twist and Red do an urban ninja thing, running and jumping on, off and around buildings to elude pursuers: police, villains or both. These scenes are a little harder to read, but you get the gist. A lot of London is used as the backdrop, including inside The Shard; that's going to look fabulous.
So sit back and enjoy the fairly wild ride. There are lots of plot twists and turns, and the art side of things is fascinating. As is the ending. Not what you expect.
