Shopping examines a sub culture of ramraiders and petty criminals in a Britain of the very near future. It centres on the characters of Billy, just out of prison for ramraiding and totally unchanged for the experience, and Jo, Billy's oh so cool girlfriend. Billy comes into conflict with Tommy, gang leader and ramraider business tycoon.
The film uses visual styles recognisably drawn from Bladerunner and Clockwork Orange. It has a good soundtrack, and a fair bit of action. It has some good performances, in particular Sadie Frost, who plays Jo, and Sean Pertwee who plays Tommy. It doesn't pass judge on ramraiding and isn't pushing a message.
Unfortunately it fails to have a message, which means that in the end the film fails. Stanley Kubrick's Clockwork Orange is frightening and powerful because it has a message for, and about, society. Bladerunner has something to say about being human. Shopping fails the acid test of meaning.
If you enjoyed The Crow, in particular the soundtrack/action sequences, then you will probably get a kick out of Shopping. If you've got time to kill, then go for the often worthwhile cinematography. But don't believe any hype, or you are bound to be disappointed.
