I'm probably the only person who enjoyed Endless Eight in Haruhi. I remember watching it as it was airing and laughing after week 3 when people were saying "wait it's happening again?". The most entertaining part was listening to the way the voice actors changed inflection each episode and looking for the different animations. Like "wow, they really made them do this eight times instead of just reusing the same recording each time". This isn't nearly the same since the story is actually progressing, but it's still entertaining. Hopefully the title of tankobon 2 is "chapter 8" just to troll people more.
The more important issue is, when will we resolve the underwear situation? We assume that she pulled him into the closet because she finally figured out her nopan status yet that just completely disappeared and now it's "does he actually hate me" when he just spent the entire day literally trying to defend her backside. Obviously not something someone who hates you would do, but then again this is a romcom so I expect stupid statements that lead to misunderstandings to occur.
