History is never entirely accurate. Its always the results of conflicts between several groups and the history that is remembered is predominantly that of the victor. 
The only way to truly understand the situations would be to examine them from the point of view of each of the groups involved. Unless we want to have several versions of the "Story of Us" we simply have to be satisfied with a sanitized version which is somewhat biased towards the position of the British who won. 
Hopefully it is a good, entertaining series and it provides an accurate time line of the main events and that it encourages our young people to find out more about the history of our country from the perspective of all the groups involved.
