Two stars is being generous. A lot of the prompts were repetitive or just variations on the same basic idea. While there were a few gems in there that sparked some interesting responses from ChatGPT, the overwhelming majority felt very generic and didn't offer much beyond what I could come up with myself. It saved me maybe a half hour of brainstorming, but not worth the price. I expected more originality and a wider variety of prompt types. Disappointing.
