It's a story of a young biracial boy and his mother during the German Blitz of London over several days in late 1940. Rita (Saoirse Ronan) is a working-class single mom working in a munitions factory who lives with her musician father, Gerald (Paul Weller), and nine-year-old son, George (Elliott Heffernan). After the Blitz begins, Rita sends George together with a group of children on a train to the safer countryside. George is resistant, partly because of the racism he has faced in the past. He escapes from the train about an hour out of London and tries to return to his home.
The film follows George's spectacular adventures, both positive and negative, over the next several days and Rita's desperation when she learns that George is missing. A flashback to around 1930 briefly introduces George's father, Marcus (CJ Beckford).
"Blitz" features some great acting by Ronan and Heffernan. However, the script and the cinematography are overwrought and unbelievable. Computer-generated imagery makes it seem like half of London is aflame in three days. The script contains many partial stories with inadequate context and resolution. Style is featured more than content, which is a rotten shame, given the quality of the acting.
