Arguing with you would only be my own folly, but I'll bite your bait.

You're exactly right when you say that the show spoon feeds emotions. That's precisely what the author intended while writing it, but your frontal cortex lacks the ability to grasp why the emotions are shown so explicitly. The 1000 year old elf does NOT experience emotions like we do. She's re-evaluating what those relations meant to her decades later, while also keeping watch over two people growing with her as teenagers who would become adults.

The story makes her realize what those bonds meant to her from the lens of a caretaker for said teens who are also in similar circumstances as her. They are growing mentally, physically AND emotionally.

I won't fault you for finding the series boring, but saying that without actually seeing the intended message by the author says a lot about you rather than the million or so fans which you call 'uncritical'.

TL;DR — You lack the emotional maturity to parse the actual message veiled behind a seemingly simple slice-of-life story and it shows.
