Cutting-edge research is by nature difficult to understand. You have to know everything that lead up to the work to understand it, plus the new stuff being built in the paper. It's difficult to keep track of so many layers of abstractions, and unraveling them all for every statement until you have understandable chunks would make the paper too long and unreadable.

We already use a subjective measure for rating explanations. It's called elegance. Academics tend to prefer shorter, more elegant proofs in my experience. It just takes a long time to get there. If you want to understand the latest research, you have to be a specialist in that subject area. Even the elegant proofs can require years of study before you have enough background knowledge to understand the concepts needed to make it digestible.
