New here, I've been a lurker but now I decided I would start posting.

I am midway through the DT series, I am just starting Wizard and Glass now. For some reason over the years I've been spoiled as to what happens in the series: i know how it ends, i know the fates of most of the main characters. While it would've been better to be surprised, I still have enjoyed reading the series despite knowing what happens. I say this so that you don't shy away from spoilers when answering my question:

A lot of people complain about the later books and how there's a decline in quality of writing. Do you agree with this assessment? I ask because I sort of want to tailor my expectations so that I don't feel immensely dissapointed.
