From Wikipedia:What is the Willis incident?
Here is an account of the incident, with Ellison's response quoted at length.Ellison was presented with a special committee award at the 2006 Hugo Awards ceremony. His onstage behavior was bizarre, including sucking on a microphone and culminating in his groping Connie Willis' breast. Ellison subsequently complained that Willis refused to acknowledge his apology.
In my case, I can reread all of stuff with no issues . What I liked most about his stories is they made for uncomfortable reading , they made you think about things . Make the reader think and I think that I can safely assume that was one of his motivations for writing. He was a teacher and that was how he taught. I learned a great deal from reading his stories,introductions and essays. Harlan Ellison was one writer that im glad I discovered.Times change and I change.
Back in the early 1970s when I read “Dangerous Visions” I hung onto the brilliant Harlan Ellison’s every word. Forty five years later, I read "Again Dangerous Visions" and found most of it exceptionally poor, and I particularly disliked Ellison's own introductions and his apparent constant need for drama. I'm afraid the same goes for those short stories of his that I've read: I found them impressively powerful and shocking at the time, but now prefer not to read them
While we all have our struggles of one kind or another, I do think it must have been particularly difficult being Harlan Ellison.
