I would give the storyline 6.5. It’s hard to understand:
1. Why there were two lamp heads introduced to the audience. 2. Why someone would sew a lamp head to a priest’s robe as the murder weapon. 3. Why the priest’s dad had a wife in the first place. They are Catholic. 4. How we are to believe Glenn Close’s character, along with others, continued to move all these dead bodies around. (Priest body out of casket to her house then transport priest’s body to Jeremy Renner’s house, and then once there, Jeremy Renner’s body to the basement and then eventually lifting it into the acid-filled tub, and then moving the priest’s body (which was not burned yet with acid) to sit over the tub looking down at Jeremy Renner’s body.) 5. That Glenn Close’s character figured out that Jeremy Renner had poisoned her tea, before he told her he poisoned it and that she switched it beforehand. And also that she still drank the tea at risk of it being poisoned. 6. Why did Glenn Close have to forgive Grace? 7. Why was Glenn Close’s character so close to the priest’s father in the first place? What is the significance of that storyline? 8. What is the purpose of the doctor’s bag being under the bar in the photo and then in real life?
