This series has absurdist humour as it's selling point, but only insofar as one character and his family are able to reasonably do with the limitations of Japanese fictional sensibilities.

It has some mysteries to move things along, but not much else moves in terms of character development or overall plot.

If you want some light reading to waste some time, and don't mind the some occasional metaphors, you might consider this.

If you want super deep and high quality writing, you'll probably want to read an actual literary classic.
