If a slice of life story has something going on, then it's not pure slice of life, duh. That'd mean it's mixed with something else like comedy, romance, etc...
This is a true slice of life story, not exactly the easiest thing to write about.
Whether the art is "good" or not is a matter of opinion. However, I don't think you really have the right to criticize any part of it if you haven't read the entire thing.
