 Katy Evans is doing one giant mistake with this series. Of course it's just my personal opinion. I am sharing it nevertheless for what its worth. 
 The characters are just too intense! Every time I think that here they go, now they'll laugh a little, they go all high strung again. It is great to see people that invested in their emotions but nothing in this world is that one dimensional. And when it is, it doesn't exist for long. This is why it is difficult to relate to Callan and Olivia. Their relationship felt like the rehashing of the intense, edge of the seat, no laughs version of the two couples before them.
