I haven't played much TP yet. I've barely started it. And sorry, it looks bad. It looks bad even for a GC game. The textures are really awful in the environment (though the characters, and their modeling, is excellent). The game has its visual high points, but overall I find the game kinda displeasing to look at.
All the 2d games have artwork that is simple, effective, and timeless. The 3D games, particularly Ocarina, which was once hailed as the greatest game of all time, looks poor to the point of being unplayable. I think TP due to its muddy textures will suffer the same fate. WW won't since it went with a style that's not reliant on detailed texture maps.
3d games should have a jump button. Being unable to jump is a holdover from the 2d games that does not work in 3d. If you think the puzzles are good now, imagine the things they could do if they added a jump button. It would also open up more combat possibilities. The series has held on to not jumping through the course of 4 3d games now, and it feels just as unnatural as it did in OoT.
And believe me, I am hardly a graphics whore, but I do have standards, and I know Nintendo can make very good looking games. OoT was great looking in its day. WW is still astounding and unique looking. TP is, at best, extremely uneven. I expect Nintendo's flagship titles to be the best looking on their systems, and TP doesn't even stack up as an impressive looking GC game.
