Unique!
This was a very good movie. If you can call it that. Educational, easy to use, interactive and fun to watch aswell. Though the material itself is quite brief, this doesn't spoil it one bit because of such a good concept and the simpleness makes it less tedious.
If you make any more like this (possibly covering other battles or indeed other wars in our history) you should perhaps make it longer, wit more detail in the battles and descriptions etc, but keep it quick. I can't really fault this.
