Aonuma has been the main one controlling the series since Majora's Mask, not Miyamoto.
Well that explains most of it then. The early games that Miyamoto had control over I enjoyed. And I really did like the trade quests from Link's Awakening and Ocarina of Time. Those are examples of fun puzzles, something that isn't incorporated into the adventure game enough.

And while we're on the topic of Legend of Zelda, I'd just like to point out that some of Miyamoto's inspiration for the series came from the Ridley Scott movie of the 1980's - Legend.

Very good movie by the way, one of my favorites of all time. I recommend everyone view it at least once.
