Well, the comic was gone for 15 or whatever years. I am assuming the folks who enjoyed reading it are mostly still alive. I think if you regularly read a comic there is a decent shot you would check out the show, even 15 years later. But at the end of the day those 15-35,000 people really don't matter much for ratings. As for whether we had a thread here, there is one with 475 posts, but folks seem to have lost interest by mid-2018, so comic nerds clearly weren't the force behind a season 4 getting ordered.
