Hi DKervick,
Maybe the positive spin is that you’ve assimilated so much that the new material just seems repetitive… 
I’ve been enjoying Bhikkhu Sujato’s recent talks here: Bhante Sujato — Encounters With The Buddha's Words — 2019 Buddhist Library Sydney
In particular, the talk about “The Ant Hill” had some really interesting analysis of how to look at suttas in different ways, which was then applied to MN 23.
