Watched after the first anon review was posted on here. Groups of episodes throughout this series vary a lot in comedic value and originality, some feel redundant or like worse versions of pervious ones. The main character, for writing and theming purposes, can't learn from all the events he goes though and reverts to a severe hikikomori life style a few more times than I felt were necessary. N.H.K. is unique enough for a one time watch if you are familiar with/interested in the Herbivore Men phenomenon in Japan.
