I think they are pretty good. I feel if you read a book and it moves you to think out of your norm then the book did its job. One scene in the book sticks with me. We often talk about sheep, the people that are not awake and very unprepared. In the book there is one character, disaster is headed their way and to stock up on food, she buys bags of frozen food. It was a laughable, eye rolling but also sad part of the book. If a giant comet was headed this way, there would be a percentage of people that would stock up on frozen food.
