Gonna be checking out the second episode later today, but for the bolded, that's actually just going make it be more convoluted because the only times Umineko had any relevancy with Higurashi was with the poems at the start of each arc, and the very final scene where Bernkastel (who suspiciously looks like Rika in another life) goes up to a young Miyo Takano and tells her to go spend time with her parents. Around the time where her parents were going to go for a drive and get killed. It's heavily implied this may have been the moment that made her turn apathetic and search for a need of entertainment (in the form of chaos), or she may have always been this malicious and she did that on purpose to see what would happen to that world should Miyo have not pursued the Hinamizawa Syndrome research. See: Outbreak.
The first episode already fucked this up by not incorporating Bernkastel's poem or making any hint to it whatsoever. The 2006 anime incorporated anime-original poems in the episode previews, but instead of getting one of those at the end of the first episode of 2020, we get red-eyed Rika. Gag me.
Now if it's a reinterpretation, then I hope it does a good job at it. Higurashi confirms there are multiple worlds, but we only get to see five, maybe six (because Time-Wasting is a flashback arc that happens prior to every arc) of them before Massacre happens (the PSP/DS ports and manga add some original arcs prior to Massacre, but the main game has only the five worlds). Some of them play out the same way, though, but others had slight differences, although I'm extremely worried Passione's fucking this up from the word "go". I want this to be good for the sake of the newcomers because I don't want newcomers getting the wrong idea about Higurashi, but I'm just really disappointed that they're just taking cues from Deen's adaptation more-so than either putting their own spin to it or by properly adapting the sound novel. Cutting out the game club scenes is a horrible narrative decision I can't believe they made.
