This show was pretty funny I must say. Slice-of-life/comedies definitely aren't my favourite genres (actually I'm having a hard time finishing most episodic shows), but this series was a pleasant surprise! It doesn't have much of a story (like most shows of this genre), Kana's mischiefs and Chiaki's temper highly makes up for it!
It was similar to Lucky Star in almost every aspect, but it was also a lot better than LS in each of them :D
You won't find any 10 minutes useless dialogs on how-to-eat-a-chocolate-cone in Minami-ke, and you'll find characters to be 10 times less cliché. *winks
Plus, Minami-ke has Mako-chan.
