And what would be the need for the two opposing views of a show? If you go about obsessing over a show, it would seem to me that you really like it so why doesn't your score reflect that? If it was really just a run of the mill show then why don't you feel that way about it? My guess is that you picked up this "critical" stuff from elsewhere. If it's possible that a show you scored 5 or below( average-bad ) was enjoyable enough to obsessive over then it's possible to think that a 10/10 was immensely boring and/or not worth talking about. Does that sound right?
I'd recommend Bakemonogatari next btw and if you can't get behind that series then give Katanagatari a shot.
