Well, out of all dramas here, I watched only Bakaleya, but I think you don't understand one thing. The low rating is because of its air time. And Bakaleya aired in the night. So its rating is pretty good for a night drama. So your list here is quite confusing. Maybe other dramas are the same.<br /><br />edit: you can see the time on some pictures. Taburakashi Daikou Joyuugyou Maki is the same, Teen Court too. <br />So it's quite a bit difference between dramas in prime time and drama at night. You can't compare them. But it's true the worse ones ale always at night, but it's not a rule.
It started good, it was interesting but really, when the writers were switched, it became so boring that I'm surprised I even watched it through the end. Great disappointment.
