I like Amy & Bernadette but this show is like FRIENDS in it's last years everyone is becoming a caricature of how they started.
I started off not liking Bernadette, I thought that storyline and marriage came way too quick. I loved how Amy was a female Sheldon.
Now I feel Amy being a horny woman is lame and completely out of character, it's not growth, it's just weird. And Bernadette is fun, but not what she was like when we met her, but in this case it's good.
