The enemy may have changed but the name of the game is still the same - the US is invaded by a foreign force and a bunch of youngsters vow to defeat them in this reboot of John Milius's 1984 action film.
Set against the economic crisis the Soviets are replaced by the North Koreans although initially the invading force was reportedly Chinese until some bright spark realised China was a lucrative market.
Chris Hemsworth is an Iraq vet who leads the kiddie resistance movement The Wolverines, named after the high school football team. They include Tom Cruise's son Connor among others.
Directed by stunt co-ordinator Dan Bradley the action scenes are as fun and riveting as you would expect but it is all woefully jingoistic.
The Australian film Tomorrow When The War Began tackled the same premise with more nail-biting drama and suspense.
And it certainly doesn't solve the mystery of how and why North Korea would invade the US.
