You made the OoC typo twice now, I'm not sure how. Anyway.
"Poetic" is too vague and personally defined to argue effectively, but the writing never stood out to me. It's decent enough, but most characters have fairly limited lines (Zelda games aren't oriented around dialogue or NPC interaction, anyway), and there's not much room for development. It doesn't hurt the game or anything since it doesn't rely on that, but most of the dialogue struck me as just, standard dialogue. Calling the story "deep and multi-dimensional" is a confusing point for me. Evil force wants to do evil stuff because that's what he's into. Heroic hero has to stop him. It's more or less the same story as every Zelda game, and for that matter, almost every game ever. The overall setting and lore of the world, while probably stronger than most previous Zelda games, is still not particularly impressive in the medium.
Cutscene direction, I have nothing against. Memorable characters...that would be easier to discuss, if I remembered half of them. Almost everyone who isn't Link, Ganondorf, or Zelda (who have about 2 paragraphs of dialogue between them) is a more-or-less irrelevant side character. The game does a good job of making most of them interesting for your brief interaction, but I would be hard-pressed to give the praise of "MEMORABLE" characters to a game where most of them are people you give or receive an item from once and then never see again.
Aside from writing and characters, the things on the list I didn't jive with were challenging puzzles and a sense of changing the world. OoT was probably the easiest game in the series when it arrived, and that was actually one of my main gripes after playing through it. I'm fairly sure I beat it without dying once. The cutscenes were fun, but it killed the mood for me when it dramatically introduced a boss who was dead ten seconds later, and all the compiled items I had access to would feel more interesting if I actually needed anything other than the sword and boomerang for uses other than opening doors and such. I can't clearly remember a single puzzle from the game, as opposed to one with much more puzzling puzzles, Lufia 2, which I haven't played in even longer. Changing the world, well, not much to say outside of "I don't see it". The world is changing because of the events you're questing around, you're not really doing any of it. Clearing a dungeon doesn't generally have much effect beyond maybe a couple NPC's who have something to say about that dungeon.
Note that I'm not in any way trying to say it's not a good game or that the above reasons invalidate good reviews or anything. I'm not going to downrate Tetris for not having a story, for example, and the Legend of Zelda games have never really been about story. I just don't think it really deserves the highest possible praise in those areas.
Yes, it's OoT, not OoC. My mistake! I'm not really sure I understand the inclusion of the time spent with characters while making your argument as to why they aren't "memorable" enough for you. That's the very reason that they ARE memorable. Because NPC's that I have brief conversations with are written so well that I do remember them, I have for 10 years. That kind of says something, yes?
-Sheik (Zelda) that character is written so well that I had no idea it was Zelda while knowing it was the entire time. The dialogue between Link and Sheik was great.
-The Gorons in general. Especially Darunia. It gives a real sense of a culture, a real, living culture. The same is said for them in Majora's Mask.
-The little girl in the Lost Woods who is waiting for you after you are running back to him with the medicine you had the witch make you out of the forest mushroom. I remember her..why? Because she's [censored]
creepy..written so well that she left a lasting impression on me with her creepiness.
-Ruto, the princess of the Zora. The cuteness of this character in Jabu Jabu's Belly is almost unbearable. She's stubborn, cute, and knows what she wants, just like a real princess. The whole "love promise through time" thing is also fun. It's memorable.
-The gate-guard outside Death Mountain that wants you to go get his "son" a Keaton Mask, yet wears it for the rest of his life himself. Hilarious.
Need I go on? The characters are brief, but if they weren't memorable for those brief moments, I wouldn't remember them, and I do, vividly. The game is very well written.
The game has strong cinematic elements. The cutscenes are one of my favorite parts of the game. I feel it's a movie that I can participate in.
