No, it's one of the best. It has amazing dungeons and great locations. Wind Waker is the 'worst'. It's the opposite, just a few mediocre dungeons and an overworld that's the least interesting. Even though Twilight Princess isn't exactly hard either, Wind Waker is even easier (though 2D game The Minish Cap takes the cake on that part).
To me; Ocarina of Time > Twilight Princess > Majora's Mask > Skyward Sword > The Wind Waker
All are still awesome games, even Wind Waker.
