Much as I love most of the backstory stuff in Matsuribayashi, imo the arc falls well short of Tsumihoroboshi and Minagoroshi. Then again, no matter how hard I try, I can’t think of any possible way any 8th Higurashi arc could have surpassed those arcs (I wasn’t satisfied with the console arc Miotsukushi, either).
Sometimes part of me even wonders if Higurashi should have ended with Minagoroshi (with maybe a slightly different ending for that arc). Don’t get me wrong, it would still be strongly hinted that Rika and her friends would win in the next world, but the reader would have to believe that.
Then again, the other part of me thinks this is an insane idea and that I would have hated such an ending.
(Umineko spoilers) Also, Umineko would probably make people believe that Rika and her friends didn’t win in the end. Because Bernkastel.
