I don't know much about Tantulus, but I think for what it is, it's fine. Not spectacularly great as a remaster, but it does show improvements graphically. I can see the graphics are clearer than they used to be. I don't know how much more are they going to add, but we'll see.
As for the amiibo, I like the design of Wolf Link and Midna. At this point, I don't know what people want amiibo to be used for. I think the new challenge is interesting and it does provide a reward that you may not necessarily need. Plus, we don't know how it connects from TP to Zelda Wii U.
