Three stars is probably fair.  There are a lot of prompts here, I'll give them that.  However, a significant portion felt generic and not particularly helpful.  Many were repetitive, offering slight variations on the same basic idea.  While I did find a few gems that sparked some interesting AI responses, the overall quality wasn't consistent.  It felt more like a bulk dump than a curated collection.  If you're looking for a large quantity of prompts and don't mind sifting through a lot of mediocre ones, it's okay. But if you're hoping for high-quality, unique prompts, you might be disappointed.
