Call me a fanboy, Haru-tard, Haruhiist, otaku or masochist, I've really been enjoying the new ways the Endless Eight episodes have been shown, I also love all the one off special new additions, such as the playground in episode 6 (ep 5 of arc). The repetitions have also ensured I have learnt new Japanese to use whenever I visit Japan, such as "denwa" and "I Luv you".
There is also something about Haruhi being my first proper anime series which ensures it will always have a special place in my heart.
That being said, it just about breaks my heart watching the new OP each episode, wondering if we will ever see the other fantastic characters again (ie. worst case scenarios include Endless Eight NEVER ending, or the series becoming so hated that KyoAni dumps it).
Hopefully Endless Eight ends next week, and then we get something new like the Sigh.
