Like any sane person, I am a casual enjoyer of this show. It's nothing special, but it is fun, heart-warming and generally wholesome. I feel this season suffers a little though as they try to do multiple "missions" in a significant number of episodes which leads to it feeling more dry than the previous season. "Missions" can feel way too short like they were meant for a skit rather than to be part of an actual episode. Some also feel like they're cut off short leaving bits of them out just to make space for something that feels like it should be part of it's own thing.
I seriously don't think anyone would complain with a spin-off series that just takes the ideas that don't fit into a full episode and put together a bunch of those for the spin-off.
All of that being said, it's a good show with some episodes being way more interesting than others due to this issue. But if you love slice of life, you'll love this series. In all honesty they're probably just saving most of the best stuff for part 2.
