So, if you judged the series based on the first season, give it another chance. Sure, the characters don't change much, and the character dynamics are also much the same, but, even if predictable, it's entertaining enough to keep you wanting to see the next episodes as soon as possible. Basically, it works pretty well, as long as you accept it for what it is. This is not a philosophical high-minded science fiction project. It is what is meant to be: a "light" family oriented series with enough moments to keep you glued to your seat.
