Not to pick a fight, but I find it ironic that you would say that here. This show presents Japanese in a way you can't find anywhere else. If you want traditional Japanese lessons, buy a textbook.
I thought the 質問コーナー thing was a good way to break it up and assist with the show pacing. Was a bit surprised how much of this show's material I already knew. Must have something to do with that crate of textbooks at the back of the room I rarely touch.
