In the first couple episodes, it was a nominal reflection of actual school life.
With each successive installment, we've gone further and further towards the internal/fanciful interpretation of it. This is what you'd expect to hear in a game of telephone or read a troll post.
It's funky, it's over-the-top, and it doesn't match 1-for-1 with reality("did it ever, tho?"). This is more a reflection of a teenager's impression of high school goings on, as opposed to the (warped) reality of it.
"It's been a weird cartoon since Episode One, Harlequin!" you say
Yes, I know. Alpha-Nuva's just letting his freak flag fly a little higher. It's good stuff, especially for exercising storyboarding/keys while still letting go. I appreciate the fuck out of it, even if I'd be interested to see what AN would do animating the Prince (from Snow White).
It's a good cartoon. Frustrating that each episode takes longer and longer, but it's one dude. It takes the time that it takes and it's obvious it's being done for fun more than anything else.
