Actually, I quite like it. In my opinion, the chronological ep. 14 was relatively boring, and would've been extremely
disappointing if it was shown as the last episode. Adding an episode between the two murder episodes makes you want to
know even more what actually happened (though I found those two rather boring anyway). But if you noticed, they're
actually building up to a massive climax this way.
In the baseball episode, you see a snippet of Haruhi's chaos form or something, where they mentioned something about the
end of the world. In the computer president episode, Koizumi mentioned that his fireball was about 1/10th of his full
power. In the recent episode, ep. 10, Asakura said something along the lines of "no wonder you felt so weak"
to Nagato, indicating that Nagato wasn't using her full powers either. This leads up to a conclusion, and predictably a
titanic one, in which everyone will be using awesome super fighting abilities to save the world ^_^
Then again, that's all just my speculation; I haven't actually read the manga or anything :P So in conclusion, if they
had actually shown the episodes in order, it would've been boring, because the ending isn't spectacular, and the climax
of the series would've appeared half-way through.
Oh, and yeah, this is really old stuff. Anyone who really enjoys watching Haruhi should've picked it up easily a while
ago.
