The Floating Castle (Nobou No Shiro) (Blu-ray release 2013-5-2) is a movie adaptation of a novel about the lord of the floating castle (on a lake or surrounded by farms) inspiring his 500 people to defend the castle against an army of 20000 in feudal Japan.  It differs from conventional war movies in that it is also a comedy, but the tone is incoherent.  The setup toke too much time.  Some of the war scenes are nicely done and offer something new that is not usually seen in American or European war movies.  In particular, the invasion by flooding the castle, and more importantly, the amusing way to counter it, are very special.  Although I think it is a flawed movie, individual scenes are great, and there seems to be many people who like it.
