It's not that great. This does explain why there are a lot of artist/writer changes. This part in particular caught my attention:
"When an artists like Dan Jurgens, one of the fastest most professional in the industry, when I was working with him on Teen Titans, he was always he was three months ahead of schedule. I was having a hell of a time keeping up with him. On Green Arrow, he was basically trying just to make the deadline and not be late, because kept changing their mind on the stories."
