Got the game a few days ago. I 100% cleared both temples in Woodfall and Snowhead and got all the masks and goodies I can up to this point. So my opinion so far? As someone who dislikes the original, I think the changes have made me reconsider it's low spot. It lost all sense of tediousness that I could hardly call a challenge or genius move. I love what they did to the save points. I love how you can skip forward to any hour. In the original, I got frustrated that I had rush out of a temple, and find a save point just so I could save. In the original, I slowly lost interest in playing further when I had to wait for something to happen. The original felt tedious. And that was a huge killer for me.
While there was one change that felt poorly executed to me (that being the Deku Link change), the rest of the changes so far have been more than tolerable for me. I am surprised people could start an uproar over these changes. I honestly and personally think they made Majora's Mask into an actual good game. And on top of that, the world looks so much more surreal and pretty.
As for where it is now, it went from third worst to top ten for me, probably tenth of ninth for me.
I have the Zora Mask, and after fooling around with it, I now head for the next temple.
