Liefeld exists as something of a paradox in the Comic-book industry. Though critically panned by almost every critic worth their salt for nearly every project he's taken part in for the past decade, his presence on a title almost always brings about a sales spike for at least a short while.
Some have speculated that this represents the fans who loathe him buying the book so they can criticize his bizarre artwork, while others have suggested that he has a secret fan-base who remain silent while buying his books in large quantities. Given his seeming inability to keep any comic book of his own going for more than a few months at a time before poor sales or other financial difficulties kill it, it's difficult to say who this fan-base is made up of or what actually motivates them.
