I think Abby Jimenez is great at handling trauma and hard topics, but OMG I cannot stand when the whole plot could be solved by one single conversation. 
Kristen was really frustrating, making up her mind and deciding that Josh doesn't deserve a say, and Josh felt so flat. The only thing I can remember about him is that he liked/fell in love with Kristen, but he didn't have much personality outside of that.
