I liked the tear collecting, I loved the Twilight sections of the game, i thought they looked absolutely wonderful. It was a bit of a shame having to keep your sense mode on thus denying the sight of the gorgeous Twilight but I still managed to find all the bugs when i was standing over them on the map thus I was able to enjoy the twilight more, the tears looked wonderful and their soft ethereal glow was a marvel to behold visually just like the Twilight. Of the three I preferred Eldin's the most. There was a bit too much trekking back and forth between location the third time around but I still kind of liked that because you saw the Twilight everywhere, its such a shame you get rid of it so quick.
As for the golden bugs, I love TP so much that I love to load it up even when there is nothing to do, and I left all of the golden bugs until I had completed the game and then went looking, it was so good exploring the entirety of the game looking for those golden bugs, it took me ages to do but i wasn't complaining because i enjoy the game so much. Now if only Wind Waker had a lengthy side quest like that...
