First off, the sound is utterly fantastic ; P
Seriously though, apart from having a nice rhythmic title, there's little to say for this show other than the obvious. The character designs are attractive (aesthetically as well as... well, you know), and it's just as well that the overall animation is shiny and crisp. The animators do love them some still shots, though, as the viewer takes a trip down memory lain to the sights of immobile children, forever on their way to school. And if you think the male protagonist's eyes are unsettlingly large, then join the club.
Otherwise, the show is every bit as contrived as it has a rite to be... arguably more so. It's your standard "fling with otherworldly beings" excuse for some good oldfashioned fanservice, with some particularly stunning kiss scenes, courtesy of the aformentioned animation. The show suffers from the same affliction as all those that came before it: all the relaxed campiness is eventually bogged down by pointless drama. Not to give anything away, but there's pretty much nobody in this show who wants the two main characters to get together, or at least is willing to let them do so without a fight. I understand that true love must overcome obstacles, but this is a show about fox spirits hitting on prepubescent high schoolers; the realism ship has already sailed, you can stop swimming after it.
In short, the episodes where the focus is on silly romps and startling degrees of fanservice tease (seriously, not an episode goes by where you "think" you saw something) are the best, because they most successfully attain a certain aspect that Kanokon is striving for. The drama bits are bearable at best (if only because they lead back around to said silly romps and fanservice) and frustrating at worst (more so than said false starts in gratuity). It's not bad by any means, but don't expect any sort of satisfying narrative out of this show (it's only 12 episodes long, for pete's sake! Minami-ke managed 13 easy, and it had less plot than a shoe). Kanokon is the chocolate Easter bunny of anime: sweet and cute on the outside but inevitably hollow (and there's more where that came from as I'm sure you already know).
Also, having just read back over this, I'd like to apologize for my rampant use of parenthesis. I promise I'll work on that.
