Another surprising tv series from japan and this is a goodie. It grabs you from episode one and for the bulk of season one you are always wanted to find out what happens. The character development is good, so you begin to care for the princess and the various JSDF troops involved. The only issue is by season two it becomes a bit too predictable, as well as have a number of good characters missing. Apart from that there are a number of simple things which could be done to put the tension back into the show, but as of now there is no season 3. SEason 1 and 2 are well worth a watch.
Parents will need to be careful letting their children watch as this show, like many from japan, deals with very adult and confronting topics. But there is no fan based content here, so nothing too naughty.
