If you don't judge them differently, do you feel that a "conlang" shouldn't be included unless it's done well, or does it just factor in slightly to how much you enjoy the work as a whole? Would it ruin a book that is otherwise ok but not great? Would it sour a book that you'd otherwise think is fantastic? Would you still enjoy a book that is ok, but complain to fellow language enthusiasts about the poor conlang work?

For myself, if the language was based on a real language, I would understand if someone just took sounds from the real language and tweaked them slightly to make the "related" language, as long as the tweaks were consistent; Whereas, if someone were deriving a standalone conlang that was supposed to be related to a real language, I'd want to see how they derived things from a shared proto-language. I'd also accept if things were a little too similar to English (or again, the conlanger's first language) especially when it came to phonology. I personally have a love of θ/ð even though I know they're rare phonemes cross-linguistically, so it would be unfair if I judged fellow conlangers who are also writers for similar things.
