It wasn't as good as 3
One basic reason was because the humor was less greater than last time. The animation was not as good as 3, and there was less talk. The skipping of the Water Boss really blew it up.
The only few good parts were Link's sudden bravery. Now that the Shadow Temple is your next step, maybe you should give the monsters a funny sense of style, just like the Flare Dancer in 3. I think it's running out of ideas...
If you run outta space, lower the graphics. The graphics matter less than the story.
But as usual, animation is keeping improving. That's a good fact.
