Zoku just feels like a retread of the first season with Wahei once again being trapped in his own harem and like all harem anime, not doing anything about it except being a very nice guy. Okada Yoshikazu tries to fill the series with entertaining storylines until the end but they all just seem like filler. From Kase Ryo to Hasegawa Kyoko's sex friend nothing interesting happens.
One could argue its more of a family comedy than a story about Wahei and Chiaki but the conversations between those two are the only thing that kept me watching until the end and everyone else is just dull. Some may find this show like comfort food but to me it feels like forgettable fluff.
