Brave Hearts: Umizaru (Blu-ray release 2013-1-18) is the 4th movie in the Umizaru series about some Japan Coast Guard rescue divers carrying out various different types of rescue missions.  Although it still follows its own formula, I’m pleased to see that this one is a little different – it spends a significant amount of screen time in the preparation of the rescue.  The actual rescue part of the story is done very effectively, even if it feels shorter than the previous movies.  If there is one thing that is bad about this movie, it’s the really fake CG showing the plane crashing into the sea.
