My understanding of the reviewer scores is that if the review is even only 51% positive, it's counted as "fresh", and if it's only 49% positive, it's counted as "rotten". So theoretically the two could be reconciled; if every reviewer was giving it a 51-60% positive, and every audience member was giving it around a 56% positive, then ... everybody's saying the same thing, and the only differentiating factor is how the reviewer score is counted?
Could be, but my point is more about the (now) 51% viewer composite score itself. Some say it's so low because of bots and trolling. But I don't think there's any way to know how big of an impact that really has, especially as the score keeps getting lower and thousands of new ratings come along.
