Finally beat it too... I think it is my favorite 3D Zelda game... A Link to the Past is still tops in my book but I did really like this one. It's quite long but I guess most prefer them that way... me, I like the story to wrap between 15-20 hours
If it's longer than that, I usually lose interest. But sank almost 53 hours in this doing all the side quests and got nearly all the heart pieces. Gave up on getting the Hylian shield and I didn't need it anyway.
Oh, and the final boss was ridiculously easy. I was expecting him to be super hard so I even did side quests and bug hunting and stocked on potions. Of course, when you're invincible for 6 minutes or so I guess any boss would be ridiculously easy =P But even so, I'd like to try him again without the invincibility potion... he hardly got any hits on me anyway.
EDIT: Oh and this is cool if anyone isn't aware or seen this yet...
