The writer did the Witcher show, was that any good?

No. No it was not.

Before even getting on to the main points I'll point out one of the biggest problems the show had:

Witchers live a long time, this means they very often meet people when they are children and again as adults while not changing themselves that much. So stories involving a witcher can easily span numerous decades, as happened in the books and games often. The show also attempted this, however the changes between past and present were so difficult to follow at times many didn't even know it was meant to be happening and it confused the fuck out of many, even those who had read the books!

Main rant time.

The show is called The Witcher. The games are called that, the books are called that, even the Polish tv show The Hexer is about the character Geralt of Rivia who is as per the eponymous title, someone who goes around dealing with problems that for the most part deal with monsters and such. The Netflix show was more about other characters than Geralt because modern day woke agendas that ignore source material in favor of "YAAAS QUEEN!"

Wheel of Time is doing the exact same thing btw.

On top of the misdirection of the show not following Geralt, a lot of heavy lore points have been changed meaning many significant parts of Geralt's story just aren't as important now, such as his original meeting with Ciri just not being in the fucking show!

Then there's the casting: Yen is meant to be very pale [and white] hence why she wears black and silver so much because "It matches her complexion". It's an actual quote used by her at one point.

Fringilla is meant to be extremely similar in appearance to Yen which is why she gets sent to "distract" Geralt when he's in Toussaint looking for Ciri because her similarity is so striking she manages to seduce him quite easily. Of further note Fringilla is a cousin to the future Duchess of Toussaint that appears in the 3rd game DLC and also a distant relative of the Emperor of Nilfgaard meaning by blackwashing one character they also introduce likely race changes to an empire that's more or less The Holy Empire of Rome that dress all in black, use black sails on their ships, and have an extremely conservative dress scheme where things are generally black and whites/greys with only someone like the Emperor himself having additional colors on his clothing.

Want to know what this great abundance of black armor, clothes, and other things causes most other factions in !NotPoland to call Nilfgaard?

"The Black Ones".

So I'm looking forward to that one fucking exploding in their faces.

Triss is another blackwashing that occurred where someone pale with "chestnut" colored hair became someone so drab looking that fans of the books and games had no fucking clue it was meant to be her. So again a redhead being turned into a black character.

I'd say Henry being Geralt is one of the few saving graces for the show but considering he's a massive fan of the franchise himself he deserves so much fucking better than being used as a draw for normie audiences, especially after his stint as Superman was just as wasted in regards to potential.

tl;dr it's another woke, Netflix, shitshow
