You could say this is one of the highest ratings Ive ever given in a review and I dare say.
Hyouka is worth a 10 in every aspect. Its sound is great I especially like the ending songs and the story is great. Anyone who is thinking of watching this anime or is recommended by a friend I highly recommend it too. Regarding the story if you are the type who enjoys mystery (and no mystery is not horror) then you should watch Hyouka.
