EE was pretty confusing - not the plot but the decision to televise it in the way they did. It wasn't simply that they were being lazy - after all, they reanimated each episode so it's not just like a "Last Week on Naruto!" thing. On the other hand, it really didn't need repeating that many times, the repetition actually detracted from the plot.
It was too taken up with the notion of being episodic - "Oh let's make 8 eps of the same thing happening to really emulate what Kyon and friends are going through! The fans will love it!" - but when you think about it, put them altogether and you have a 2h 40m story in which only really 30 minutes of stuff happens. Sure, even if they cut it down, they'd still need to have a
bit of repetition because that's the point of the story. The point is that just because the characters have to experience the same thing 15,000+ times, it doesn't mean we should.
The reason that this is annoying, quite apart from the novelty wearing off 5 or 6 eps ago, is that it took them two whole months to do this story. Haruhi fans have had to wait two months for the resolution to a story and were also deprived of around six new Haruhi stories (depending on how you look at it, it could me more or less than six). "Endless Eight" is like the modern version of
"Five minutes and this planet will blow up!"
Despite that I've still downloaded them all... I'm such an idiot but then I think I was just seeing how far they'd take it; a kind of masochistic urge.
