I, for one, am fond of 07's compassionate kind of storytelling. I'm tired of the meta-trope of things having to be 'earned.' Humans in the real world don't come in hero and villain flavours. Everyone is valuable as a being with unique experiences, the protagonist of their own story. If at the end of the day you can save everyone, save everyone. Hell shall be empty, Protestants and neoliberals be damned.
Rika getting everything offscreen feels rushed, but I don't know if seeing her do all of those things would have made the story any more interesting or if it'd instead feel slow and predictable.
About Shion remembering having killed Satoko... Well, that wasn't Shion. In the fragments/loops of the alien simulation of Watanagashi fate, 'Shion' is actually the Mion of the other fragments. So Shion here accessed Mion's memories. There was a nice invariant of Shion never going L5 that was broken in this story when the one to do Watanagashi/Meakashi is Mion.
I think the connection between the WTC series is that the fragments are many instances of planet Earth's simulation inside of the alien ship in Haworthia's story. This could give many scenarios in Ciconia without time travel, as 07 said there wouln't be loops in Ciconia. It also unifies the material and meta world. Satoko is said to be Vier with her memories erased, as if Higurashi is some experiment in the subterranean complex. Higurashi is a game played between runs of the simulation.
Valid. Compassion is a good thing, but I feel that every time a story tells of someone who did something bad that hurt their friends due to their own insecurity, trauma and/or they were brainwashed/manipulated, it's always unconditional forgiveness and pardon, and everything will be okay again. Rika can save Satoko, and that would make me happy as a fan, but personally, what she did to Rika, her best friend, and all her other friends is something I cannot forgive since I had similar experiences with people like Satoko. Not everyone can be saved when they're stubborn about being in the right and holding you back to keep you with them for their own needs. That's unhealthy. And for someone like Rika, who sought to get out of the neverending loops, I don't understand how she could forgive Satoko that easily, with Satoko refusing to realise she was in the wrong/lost.
I was thinking the Rika solving things offscreen could be amended by having her also being in a montage of her finding small clues here and there before getting killed endlessly, like how we had the montage of Satoko learning how to use a gun, crack the code to get the H173, kill Rika, repeat. This will also show Rika's resilience. Sure, she got killed over and over, but it showed she was ready, and she's slowly gaining clues on what to do, and that this 'game' is different from the original loops she went through.
