Good or bad? This helps me create something that people may not instantly be able to recognize and helped me come up with ideas I normally wouldn't have been able to. Not to mention, I can still ask it for ideas on other parts of the character's life and constantly flesh out more about it on the spot. It's not always perfect, but it's incredible when you need something fresh and you're feeling creatively blocked.
What do you guys think? I recommend trying it for yourselves too, and form an opinion.
