The document provides feedback on the script "Heaven's Mistake". The reviewer liked that the script gave greater clarity to Katy's arrival in Hell and her explanation of powers. They also enjoyed the addition of backstory tying characters Silva and Vanessa to Katy in high school, and the inclusion of more scenes with Vanessa to develop her character. However, they suggest making Katy seem even more mean in high school to motivate Vanessa's suicide, showing Silva's attack when he dies to build more tension, and changing Katy's cancer death to an accident to make the timing more believable.
