I rated 5 as my average total rating of the four seasons. Season 4 is a waste of time. Why is the "Go To" storyline when one character kills another, they keep imagining seeing that character and it haunts them. It was overkill in this season. That is one of many problems with this season. One character I CRINGED every time she came on screen (in every season) that I could have done without and I hoped she would have been killed off the series or something is Jessica. I thought it was just me until I brought up the series with different sets of friends and family members. No one likes her. I don't know if it was the character itself or her style of acting but she was extremely unlikable.
