The ending was conclusive and good. Some of the new elements bolstered this story, while some of the more interesting elements felt a little dropped/forgotten in the name of reaching a conclusive end. Could have easily been a 5-star if some things had been polished up and different areas had been focused on. That said, I definitely enjoyed the series and enjoyed that Aveyard did not do the trope epilogue of "10 years later". It felt conclusive while leaving openings for continued writing if Aveyard and her readers want to have more later.
