I just read that article too.
Boy I really don't get why some people think these "dramas" have to be historically accurate. If I want real history, I would just read books or watch documentaries, and who is to say that those are 100% accurate, too?
I also read the original JP article on J-Cast:

How is her portrayal of Gou a "baka-hime"? Good grief, it's a freaking "drama." It's a, to a certain point, historical fiction. It's made to entertain, not to teach history. One would be a fool to believe everything in those Taiga dramas to be 100% real. So why expect
Gou to be as such?
This story is on Gou, and there is very little information on the childhood part of her life, of course many things have to be made up. Or maybe those people just wanted Tabuchi to skip Gou's entire childhood? That's not possible with Saji Kazunari being part of her life during this time.
And I saw some criticisms (not in this article, though) that Hideyoshi is made to act like a fool. In the Taiga's I've watched, all Hideyoshi's have acted like goof-balls in some way, shape, or form. Goof-balls can be wise, and Kishitani Goro's Hideyoshi has really shown his wiseness, especially in the recent episodes.
I am a history buff myself (though mostly on the Chinese side, I didn't start reading about the Sengoku era until about 8 years ago), but I believe myself to be open-minded enough to watch these dramas while not expecting everything to be true to history.
Like I mentioned before, I just started watching Nodame, I think she plays the two roles very differently. Seriously, I can't wait for her Gou character to grow into adulthood and let her acting really shut those people up.
As far as I'm concerned, I'm being entertained and will continue watching, but just had to get the above outta my chest.
