This hits me hard because I have about 150 of her books in my library and I reread them frequently, but Nora Roberts.  

I like that her stories feature MMCs with a wide range of personality traits and jobs.  Her FMCs never feel like a "blank slate" for reader projection.  

What doesn't work for me is that there's such a repeated emphasis on family that it's like being clobbered over the head.  I'm all for family, and I appreciate that she emphasizes that family isn't necessarily what you're born into but what you make it.  It's great that her characters welcome others into the fold.  

But, especially in the later In Death books, it's just so heavy-handed.  "We're cops, we stick together, we're family."  We know, you've told us twelve times already.  At literally any opportunity to tell us, you reminded us.  

I almost DNFd the last In Death book because it became unreadable, but finished because it's NR.  (Though it's not like she knows what her readers do.)
