Aoi Tokugawa Sandai (2000)

Both dramas portray Ieyasu as the protagonist, but Aoi is only focusing on the older Ieyasu (to be exact after Hideyoshi death). Both dramas however have different interpretations on the character, where TI is more on the whitewash version, while Aoi is skewed towards the "gray-character" which in my opinion more tally with the historical records.

Aoi is another portrayal of Gou-Hidetada marriage life. However Aoi started off with both of them already married (i.e. it will not start from their childhood) and focused more on the affairs around Tokugawa big family as well as more details on Edo shogunate administrations.
