While it is easy to get swept up into a sea of negativity and pick apart the fine details of a series, the reality is I feel this is a good gateway show. Could there have been more? Yes, always. However the director and production were not looking to create a flawless recreation, and openly state that they used creative costuming and sets for many scenes. The creative costuming and set designs were based on period accurate research, and then given a creative spin.
There are Japanese historians who appear in the series and speak, and a number of professionals who provide great quick info about the various events and battles. In truth, there was so much that happened in this period, a whole series could be made about just -1- historical figure such as Oda Nobunaga. Instead there was a broad review of the period that touched on many points.
I hope that the success of this series will prompt studios to take a more serious look at Japanese historical productions, and properly budget and dedicate more research and resource to them. This period in Japanese history, as well as many others, is ripe for film and deserves to be taken seriously.
So, if you enjoy Japanese history and want to quickly sink your teeth into this period, or introduce someone to this period this is a great series for you. LEt's hope that Hollywood in the future will take a serious approach to this kind of topic, and better fund and research their work.
