These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Sket Dance
Awesome Music: The 'Concentration' track does it absolutely wonderful to the moment where Bossun is 'concentratring'. Because, of course, you need to add awesomeness to the moment where he is thinking and connecting points that were missed at simple sight/heard, because in.universe it could be boring.
And speaking of, 'Cool & Crazy', when stuff is going in the favor of the Sket Dan.
Ensemble Darkhorse: Switch's Bossun drawing, a non-character, that made up in the Top TEN of the first Popularity Poll.
The series has a lot of this, as the second popularity poll revealed. Among the other notable ones are Anthony, an action figure, and Tanabe-kun, a character created by Bossun and Tsubaki in their attempt at fixing the writings in a banner.
Face of the Band: Dante in his band JardiN, though the other members have names too, there is only Dante and Rodan who have more talkative roles.
Same would be applied to the old bands that the Sket Dan were part from in the Kaimei Rock Festival. You just remember mostly about THEM as well.
"Funny Aneurysm" Moment: Chiaki in episode 4 wants to win the Pelolipop contest because her little brother said the doll looks like his deceased mothernote That is because of how similar both of them stick their tongues out.
Narm Charm: The show can be really cheesy at times. And yet, it somehow works.
Relationship Writing Fumble: A chapter in the manga, Brother and Sister, explores the ambiguous ties between Bossun's not-blood sister, Rumi, and his biological twin brother, who had been separated at birth Tsubaki. They were supposed to see each other as brother and sister, but the way their relationship develop is almost exactly like a romantic set-up of romance mangas (i.e. they have a movie "date", hung out together the whole day, and it ends with Tsubaki saving Rumi from falling off a bunch of stairs).
