Yeah, I hated that. It's like everything had to look like it came out of Twilight Princess. On 9 out of 10 characters that... Just. Does. Not. Work.
I'm all for adding detail to simple characters when it works... but when it doesn't it really doesn't.
Putting realistic denim textures on the overalls of a cartoon character... it doesn't mesh well. The cartoony proportions and simple textures are meant to be abstract representations of real life. You can't make some parts of it realistic while keeping other stuff stilistic.
At least they didn't make EVERY texture tealistic.
Otherwise you'd end up with something like this:
Eeeuugh~
Edit: It's like when I watched the Good Dinosaur. Everything looked realistic, except for the dinos and humans which looked like cartoon characters with realistic textures. It did not work. It would've looked much better with a stylized look.
