For animated chibis, they displayed a very limited range of emotions (most of the time it's just blushing); they're chibis, they're supposed to be over the top in my opinion.
Plus, too much useless fanservice and tsundereness that I find plain annoying.
The attempted humour falls flat, and everything that happens is extremely predictable.
The segment that I did enjoy was the trivia corner because it wasn' something that was necessarily repeated information - usually it was something new that you wouldn't get from just watching the series lightly.
