Writing for the Daily Beast, Lindelof explained that he struggled to deal with complaints from viewers.
"The most awesome part about being one of the primary storytellers of a popular television show is hearing how much its most loyal fans hate it," he said. "Oh. Wait. It's actually not awesome. It hurts like hell.
"I know, boo hoo for me. That's the price of doing business, isn't it? If I'm asking you to invest your time and attention in a story I'm telling, it's your right to tell me that you hate that story. You just don't get to call yourself a 'fan'. At least that is what I had always believed."
Lindelof explained that he changed his mind after being disappointed with the latest Harry Potter movie.
He said: "Based on the careful emotional logic I'd been using to insulate myself from the slings and arrows of, 'Why didn't you people answer any goddamn questions?' and, 'A golden light in the middle of the island? Seriously?' if I hated the movie... Did that mean I was no longer a fan?
"[But] I still love Harry Potter... My point is that I'm still a fan. A huge fan. Huge. And so I sincerely and genuinely apologise to all those whom I have stripped of their Lost fandom just for complaining about the stuff you didn't like. It doesn't make you any less a fan. In fact... it just makes you honest. I respect that. And I'm genuinely sorry for ever feeling otherwise."
