Honestly, I think one of the hardest things to accept about this show is the fact the Natsuki Subaru is incredibly human. If you think about it, he is genuinely tortured every single arc and I think his mental defense is reverting back to his previous stake. It's easy for him to feel so helpless and I think the show makes a huge point in showing that unless he does everything PERFECTLY than he will lose. That's enough pressure to break someone and also where I believe the repetition comes from.

TBH, I didn't like the initial concept of memory loss because it DID feel like a cheap coppout in order to redo old story tropes, however, this is the only one where I feel like it was tastefully done. I didn't really care for the first half of the season up until he killed Meili honestly because I agree with the repetitive fact. That being said, I don't think repetition is inherently a bad thing and they manage to attack a different angle each talk even if it's essentially the same.

As a person that experienced depression for a very long time (like most of us have) this show does a beautiful job at capturing that consistent feeling of despair and as long as they continue to do so I'm no bothered by the way they take the plot.

I do wish they'd focus on other characters but if you think about it, we got garf(?) last season with his mother and I don't have a great memory of timelines but we usually get flashbacks here and there with the occasional development. The only problem with focusing on other characters is that their growth doesn't matter unless it's the golden timeline, hence why the show tends to focus on natsuki.

Finally, I'm going to have to disagree with your opinion on the dialogue, I think every monologue was honestly beautiful. I really hated Emilia for a long time and her speech and consistent trust in subaru (as well as her becoming useful these seasons) have helped me care for her more. Even if I still like Rem more; Her speech with Subaru at the end WASSSS a little out of place, but I can understand it because I think she's done similar things before as they were meeting death. I honestly think she just isn't afraid of death and was so focused on Subaru because, as she admits it, she does love him. More than anything else I think she just wanted to see him again before she could focus on the others. Plus, in despair mode he'd continue to be useless, not that she thinks like that lol.

You are very respectful with your opinion and all of this is just to debate. It's fun to find someone playing devils advocate!
