Just watched episode 11. I'll preface this by saying, I actually really enjoy the main storyline (the episodes marked Melancholy of...). It's actually hooked me more so than the "slice of life" episodes scattered throughout. Not that I don't enjoy those either. In fact, I rather enjoy "slice of life" anime. So, this has a nice mix to it.
As usual, this episode has a lot of well done homages to various shows in the past, which I enjoy very much. Getting past the fun of the episode, I do like how they develop Nagato through these episodes. Makes me wonder what will happen to her in the main storyline since she's seen more than the others. She's definitely got the Ruri (Nadesico) dynamic working for her, but I like this character much more.
I didnt know the show is only scheduled for 14 episodes, depending how they wrap up the main storyline, it's probably nowhere near enough episodes to satisfy. =( Plus, we need more time for Asahina and the other guy to turn into some fun characters (currently, they just aren't.)
So far, the interesting main storyline, combined with Kyon and Nagato keep the show interesting for me. Asahina is nice fan service, the other guy is...just there (I cant even remember his name. That's a bad sign), and Haruhi herself is more annoying than anything (either this show ISN'T about her, or it falls victim to the annoying heroine syndrome. Which would be a shame.).
Kyon rules though.
