I agree with you on a good number of your basic assessments of Cube x Cursed x Curious ... well said.
Not the most profound show in the world (although something tells me if they stuck to the story and really explored its possibilities instead of serving up the "fanservice angles" it could be very interesting for me), but overall pretty decent.
So then! What have you watched that you liked thus far and what do you anticipate watching during the Fall 2011 season?
For me atm I am watching:
Tamayura Hitotose (the one I looked forward to the most)
Chihayafuru (a pleasant surprise)
Morita-san wa Mukuchi S2 (new material! yay!)
C³ - Cube x Cursed x Curious (not fully committed to this one yet)
