I would classify this as kind-of-a ho-hum Hollywood love triangle story line - a conflict between two guys and one girl - it is a bit of a twist that one of them dies ... for a while.  The computer-generated action scenes integrated with the real action scenes and the WWII planes and the attack - were all terrific film technicals.  You could tell what was generated if you looked hard, but you didn't notice if you squinted. 

The Japanese leader will impress you as a thoughtful, caring military guy who knew the consequences of his actions and didn't particularly like those consequences, but a job was a job.  I think this was cut into the plot to appease current relations with Japan.  I don't think they were that nice in 1941-45.  But, it's only a movie.  There is some pretty valid history dramatized here for those younger folks that don't remember any of our second worldwide conflict.
