'Yasuke' may have disappointed some viewers as they thought it was going to be more grounded in reality, with the main character - Yasuke being a realistic portrayal of his real world counterpart. Instead the show takes a rather different route incorporating heavy magical elements.
I'll admit that the lore of the world is pretty basic and not fleshed out at all which leads to a little bit of deus ex machina on top of Saki being kind of boring. Other than this however I found the show to be extremely enjoyable. There's nothing inherently wrong with tropey anime stuff as long as you're not expecting something entirely groundbreaking and serious. Not every anime needs to be Evangelion, guys.
Some of these reviews complain about the 'forced agenda' of the show but I really don't see it. Yasuke really was very highly regarded by most people of his time with no stigma towards black people existing other than the fact that they were foreign. Oda Nobunaga was famously interested in other cultures so it's not too far fetched to say that if he's lived longer Japan may have become a more accepting place. Secondly, homosexuality was accepted in bushido (the general warrior philosophy of the time). Having a gay character is also nowhere near the reach people have described it to be
It virtually goes without saying that the music and animation are absolutely top tier. 'Yasuke', in my opinion is delightfully fun and binge-able. Very much worth a watch. Just don't expect a masterwork or anything.
