I find Mr Griswalds part annoying, Mrs Griswald part gives the informative part. Over all it is a bit boring and not so easy to follow. I did like that they used anime as the subject to base the lesson.
The should place the kanji or hiragana of the text they are describing
Japancast is very informative, I've learned a lot from it. I find the hosts really entertaining, their different personalities make it very enjoyable. I highly recommend Japancast, as a must see. This is a 5 star show!
