Contrary to popular opinion, I think some the manga getting slower with some SoL moments is a good thing. It just seems bad because the releases are more spaced out than usual.
The genius with this arc is on the outside everything seems peaceful and the manga even gives time to normal SoL moments, but the reader KNOWS there is something very very unsettling under the peace. Once this arc ends and can be read in one sitting it would probably be more enjoyable.
