Don't finish; read a good summary if you cared about any character or plot point sufficiently.
I enjoyed it overall but in large part for the detail/immersion which it sounds like wasn't interesting enough to keep you.
All character growth and relationships were very slow burns, and so if you enjoy watching the same characters just dealing with things as they come up then you'd probably enjoy the other books as much as the first three. Satisfying arc resolution happens almost entirely at the end.
