You're complaining about the dialogue in a short video?
The dialogue did its job: It introduced a new character to the series. It wasn't meant to be deep.
Maybe I'm biased in that I *love* Kid Icarus: Uprising and the little short-intro used the humor that is present in that game - which I enjoyed. The game uses a kind of snarky, fourth-wall breaking, trollish humor that is not to everyone's taste. (And then those of us who like it, *really* like it).
I would agree that it wouldn't fit a full-scale Zelda anime, though. Kid Icarus humor is Kid Icarus humor. Expecting a Zelda anime to follow KI-writing would be like watching an X-Files episode with Seinfeld-humor... (I loved both shows, but it wouldn't work)! The Zelda series, though it has a lot of whimsy, *is* more serious and would demand more a more serious writing style. Also, Zelda is an escapist "fairy tale" style world unto itself that wouldn't do very well breaking the fourth wall a lot.
I actually got an idea for how Link's dialogue would work after seeing this topic. I don't think a voiced Link should be completely without words, but I do think he should be "a man of few words." That is, much like with the dialogue-trees in the games, Link only speaks when it's important, when he needs to. Example: Most times he goes into stores in the anime, he should just be able to point to get what he wants, but he goes into a store where the shopkeeper doesn't know what he means, so he has to politely, dryly say "Bombs, please." It could even be lampshaded, with other characters who've known him since childhood saying that "he speaks little, being more a person of action."
And most of the story-speech is carried by other characters, as in the games.
