This is a 67-minute "movie" filled with tons of stock footage. It's full of the usual cliches both in characters and dialogue. Ostensibly about the battle of Okinawa, it is, in fact, about a destroyer on picket duty around the island. It has absolutely nothing to do with Okinawa despite its title and could have been set on any number of islands, even fictional ones. There's no tension, no drama, and very little action (much of which is stock footage anyway). This movie was clearly made on the cheap and it really shows. So, on one hand, its runtime of barely over an hour makes the viewer feel like they're getting gypped, but on the other hand, the agony is over quickly.
