I really liked it, though yeah, it gets in its own way too often. I'd say dungeons 3-6 were amazing experiences, and somewhere after dungeon 2 through the cutscenes after 6... just perfect pacing and dungeon/world design.
I like the overall philosophy of the motion controls - keep the gamer active, keep the gameplay dynamic. There are a lot of problems with the details, though, big enough problems to keep the game down on their own. But I think the game is pretty weak until after the second dungeon, and the bits between the 6th and 7th dungeon are pretty awful, so there's enough of an issue outside of the motion controls that keeps it away from being a "best Zelda game" contender.
10 years, nah. It's a few years late, though - this really needed to come out around the time WSR/WM+ came out.
