Yeah, I feel like there’s a difference between a good when it comes to comics and most media. The fact that there is a comic that gets a 9.0 average on comic book roundup tells you all you need to know about the standards of the medium.
All of the stories you listed are enjoyable, but nothing to write home about. If you aren’t a fan of the character, they aren’t worth reading. Which is my criteria of good.
It does give a slight bias towards beginner friendly stories like Year One, but that truly is more memorable than anything else.
And I strongly agree that most of his best stuff is when he isn’t Nightwing. Those are all great stories.
