The main problem is she doesn't understand comedy
Comedy needs conflict, and in order to have constant conflict, you need flawed characters who consistently behave badly. Otherwise, you have dull, gutless watered down comedy. This description (from Wiki) of the "Good Place" show she mentioned that she's a fan of pretty much says it all: "The series focuses on Eleanor Shellstrop (Kristen Bell), a woman who wakes up in the afterlife and is introduced by Michael (Ted Danson) to "The Good Place", a Heaven-like utopia he designed, in reward for her righteous life. She realizes that she was sent there by mistake and must hide her morally imperfect behavior and try to become a better person."
Even though I'm a fan of "Curb Your Enthusiasm", I can sort of understand when folks make similar complaints about Larry David's character. But to not be able to get past Homer Simpson's boorish behavior indicates a level of sensitivity that just seems unsuitable for the enjoyment of comedy, let alone writing about it professionally.
