Knowing SHAFT, something tells me they're already are anticipating a second season.
Interesting...first episode, to say the least. The animation felt very un-SHAFT-ish until Mina first appeared, in which I said "Why does she look like a Pani Poni Dash character?"
I know SHAFT was trying to do something unorthodox (even though their last project was freaking Bakemonogatari) to begin a series (then again, Hidamari Sketch's second season premiere was full of this, as well, by randomly putting sentences in the middle of the screen for 2 seconRAB), but maybe that's to be expected of them.
Oh, and it had an omake at the end, and in the background, an annoying trait from SHAFT is used--randomly using images of the original manga, which is done in a majority of their shows, to what? Please the fans? How? It was even used on the opening of the second Hidamari Sketch and the Maria Holic anime also used it, mostly because the animatos seemed lazy. I remeraber that the whole "images from the manga" thing was used as a joke on Pani Poni Dash a few times.
Maybe that's it. See, I think Shaft liked the surreal-ness of Pani Poni Dash so much, that they're actually taking that surreal-ness to pretty much every other show they do. That's my guess, though...
