SKET Dance has a really sh*tty, dissatisfying ending for shippers. Total cop out. I hate that in anime and manga. Makes me wonder, have none of these mangaka ever actually been in a relationship something? It's like they're so socially awkward they're terrified/resentful of writing an actual conclusion to their story.
I'll be honest I was surprised with the ending, but at least it ended better than Naruto's.
Still, that's a story I would recommend to watch/read (more the manga than the anime, since it ends sooner).
If you watch the anime you will notice a common thing this studio has with SP.
The big boobed fanservice syndrome.
That's the only thing that pissed me off.
