just watched medaka box eps 1 and uchuu kyoudai eps 1 :
- uchuu kyoudai : good drama about family and way of life, better than expected.
- medaka box : I've never read the manga,, so I wouldn't compare it.
overall it's unique and interesting. a bit too fast paced (so many things happened in 1 eps), maybe because it's not given enough airing plan/episodes?
doesn't seem to exploit ecchi scenes to increase its rating (yet) although it's still zooming at boobs for couple times

I'll include both in my watch list
