Honestly i Loved it.
It's such a heavy read though (Think Stormlight and WOT heavy)
I read the whole series and i am currently rereading it now and picking up so much more. I must have missed a ton.
There is violence and profanity but less dark than GOT id say, but it doesn't solely focus on that aspect though.
You can only give it a try but i loved it
As a personal recommendation if you do give it a listen try the "Ralph Lister" version as it's newer and better!
