Umineko at its core is really a philosophical metanarrative that strikes at the idea of stories, why we read them, and why we engage with them. More specifically, Umineko is an examination of, and partial love letter to, murder mystery novels, particularly the ones of the Golden Age (Agatha Christie and so on). You know, the classic ones where the detective takes the suspects to the main room and goes "you did it! here's why!" and the audience goes "oohhh" at the explanation of the mystery.
One of the central debates of its story is how one goes about solving a mystery. Do you go for purely the logical approach of "what makes sense" out of a desire to 'solve the plot' no matter what, to be ahead of the detective, to prove your own ability? Or do you go for an interpretation that strikes at the story's themes, character motivations, and meaning - to look directly upon its 'heart?' Put simply, of the "whodunnit", the "howdunnit", and the "whydunnit", which one matters the most to a story?
It becomes extremely clear during the course of Umineko's story that this isn't really a debate at all. It unequivocally sides with the latter interpretation, as its main phrase "without love, it cannot be seen" demonstrates. Umineko posits that not just mystery novels, but all fiction, is ultimately a dialogue between a reader and its author. Only once a reader understands the author's message and ideas can they complete a work by offering their own interpretation. Focusing too much on what's "objectively correct" demonstrates only self-centered thinking on the part of the 'reader' - that they alone have been given the esteemed position of having to 'solve' the story.
This opened my eyes. I previously thought that stories were more like corpses. Things to be examined, dissected, taken apart, comprehended on a fundamental level, and then 'solved'. It angered me when a story I was reading for a long time contradicted itself, or ended up resolving in a way I didn't think fit
my personal theories
all the foreshadowing the author put forward
. "This doesn't make any sense", I thought, "is it not meant to make sense? To be its own world I can be immersed in?". How on Earth am I supposed to win arguments online if the story isn't always internally consistent?
But the ultimate lesson is that doesn't matter. Obviously, you can have fun theorizing and thinking about a story's lore and setting. But what ultimately matters more, at least, to me, and to Umineko's worldview, is what the author has to say, and whether or not you understood that heart. So long as that's what remains the most important to you, a story will never annoy you - unless of course, your hearts aren't in sync. Basically, set aside your ego as a reader aside and try to have a dialogue with the author. And then, and only then, can you decide "I disagree with the author's worldview" and say the story isn't for you.
I've enjoyed many stories. But Umineko is one of the very few that changed how I interact with fiction altogether. So it holds a special place in my heart.
