Awful opening and closing. However, the actual show is really impressive, particularly the art and animation.The show keeps you in the dark for these first few episodes, but the characters definitely make it worth watching. Shinkuro is refreshingly mature for his age and Murasaki is outrageously cute, not to mention 20 years wiser than the average 7 year old, but I personally like that, it continues the japanese 'tradition' of idealizing youth.
The dialogue and characters are one of the best apects of the show, if you're a fan of dialogue heavy shows, you won't be diapointed.
