I've finished a couple of shows recently.
Black Sails 
I really cannot praise this series enough. A combination of real and fictional pirate characters come together in an epic tale about the battle for control of Nassau. It is harsh, brutal, and mature, but most of all honest. The characters are truly nuanced and each of them well represented. It covers serious topics related to love (including LGBT+), death, slavery, oppression, and ambition. The music is also top tier. 10/10
BlackAdder 
On a different note, this Rowan Atkinson comedy is full of wit and hilarity. Each of the 4 series covers a different point in history with roughly the same cast of characters.
My favorites in order:
- Series 2 with Queen Elizabeth
- Series 3 with Prince George
- Series 4 during WWI
- Series 1 with Richard IV
There is also a Christmas Carol special with Queen Victoria that is quite good.
Definitely recommend if you are a fan of Rowan Atkinson's brand of comedy.
The Witcher: Blood Origin
I'm not quite done with this one as I've only watched 3 of the 4 episodes so far, but I might as well go ahead and comment. The last episode can't possibly change my feelings on this series. It simply doesn't live up to my expectations based on The Witcher. The acting is subpar. I know what emotions they're trying to convey, but the show doesn't make me
feel those emotions. There are some characters I want to like, but the depth and storytelling just isn't there. I'll finish it since I'm almost done, but I cannot recommend it in good conscience.
