The story is based on an old comic strip. Set in a Britain of the future, which is under a totallitarian government. Enter "V", a freedom fighter, sort of like a modern day Guy Fawkes.
Hugo Weaving has done an brilliant job, even though we never get to see his face. Natalie Portman is very good. And I liked the chappie playing the inspector

I would say watch it for hugo weaving

He's come a long way since his agent smith and Elrond days....
