What do you mean by that? I just finished Stardust and The Ocean At The End Of The Lane and his writing was quite lovely - but he was going for the fairy tale vibe with those books.
I have a similar, possibly identical complaint about American Gods. Reading American Gods made it clear that Neil Gaiman is very clever (intelligent, tricky plotting) and, independently, a great writer (good with words).
But his tastes are different from mine. There are sections of American Gods that are much too vulgar/crass/obscene/whatever for my taste.
This is also why I never read the sequel to Lies of Locke Lamora.
You find Scott Lynch crass and obscene? It's been a while since I finished those books but that doesn't ring a bell.
Do you mean metaphorically like a crass analogy or like full of swear words? The former would bother me much more than the latter tbh , especially since we're following orphan street urchins - seems in character almost.
