This is the first anime I have saw that air eight episodes which filled with the same thing over and over again. I'm mad at the first time, but now I understand why KyoAni decided to take such risky choice. KyoAni is making us to feel the frustated Nagato Yuki that she's the only one who knows that she's doing the same thing over and over again, but she can't do anything.
Yuki have doing the same thing 15,521 times, imagine how tired she is. If you watched all of the Endless Eight, you'll realize it. When there's nobody knows that they're repeating two weeks 15,521 times, she knows it. How painful it is when you repeat the same action everytime. This arc were designed to bore us, and to understand how Yuki feels. The main character on the Endless Eight are not Kyon neither Haruhi, but Yuki. This is my own opinion, so if you disagreed, please leave a feedback on my profile!
