Stuff happens throughout the show.An argument could be made for the latter half of Hyouka being the best.
The first half is easily the worst.
Misaki comes into the picture along with Irisu and the show improved dramatically.
Also, stuff actually happened.
Unless mundane mysteries about locked doors and ice cream are exciting.
He improved it, even. Huke's art is pretty bland and bad once you strip away the tacky filters.Yuusuke Matsuo did a far better job of adapting Huke's designs for animation than anybody else has.
