I'm not sure if being a childish comedy drama really equates to poor ratings. Marumo no Okite is a drama staring children and a talking dog, but their ratings have been quite strong, even causing execs to wonder if it will steal viewers from Jin 2.
However, i agree that the time slot may have a lot to do with it. Shitsuren Hoken, which airs at midnight, has experienced single digit ratings, peaking at 7.3% at debut. [Shima Shima is another drama in a similar time spot with similar ratings, but I haven't seen it, so I don't know anything abou it.] I wonder how dramas like Muscle Girl and Shitsuren Hoken land such dismal time slots and how the companies make money from the shows. Do they create them as cheaper, late night dramas from the beginning of production and keep costs low through out or do they look at all the dramas they have available for the season and put the weak ones at midnight+? Where do they make recoup money for "failed" dramas? Do they have syndication like they do in the US? Like maybe a drama that isn't popular because of it's time slot could gain momentum and popularity if it is reaired at an earlier time slot in the late morning or afternoon (before primetime).
BTW, these are the most recent ratings according to Tokyo Hive:
