I liked it quite a bit for the first three quarters or so but I felt the end was a huge info dump. Normally he manages the world building in a way where it's not a huge leap to understand what had happened but in this case there were multiple layers of the narrator saying "oh, you're confused?! Of course you are! Here's an info dump about the cosmere".
I've read everything cosmere, but I'm not very happy with the more recent books that expect cosmere knowledge to make the story enjoyable or even understandable. And I feel like he's getting pretty lazy with that lately (though maybe the secret projects not having a third party editor has something to do with it in this case)
