And the Fandom Rejoiced: After Dwayne McDuffie's death, rumors swirled that A) McDuffie was supposed to be the next writer on Black Panther, and B) As a tribute to his real-life close friend, McDuffie, Priest was going to come out of retirement and "fix" Panther. Sadly (or not, depending on what you think of David Liss), only the first part turned out to be true.
Fanon Discontinuity: Many Priest fans choose to believe T'Challa died of his wound, and that a new, crappier, dumber T'Challa has been running around masquerading as him ever since. The difference between Priest's and Liss' interpretations is so profound at this point that some fans are starting to speculate that this will become Fanon Continuity as soon as Liss loses control over the character.
To clarify, a story comes up in which the Ray, alienated from his friends and haunted by an enemy too powerful and clever for him to deal with, decides to make the ultimate compromise and go to the (allegedly villainous) Vandal Savage for help. In order to get to Vandal, he has to blast his way through Vandal's defenses, which he does, and then storms into Vandal's office... where he finds Vandal sitting calmly, eating a chicken sandwhich from the fast-food restaurant Ray works at in his secret identity. This annoys Ray enough that he blasts Savage, destroying the chair and table he'd been sitting at... which Vandal, completely unperturbed, then points out he'd stolen from Ray's apartment.
Mary Sue: A common complaint about Panther, and to a lesser extent Triumph and Ray. In every case, Priest's approach was that these characters had plenty of vulnerabilities, weaknesses, and flaws... but that these weaknesses, vulnerabilities, and flaws were a bit less subtle than "allergic to green rocks" or "dumb as green rocks".
My Real Daddy: To Panther, Ray, and Vandal Savage especially. Triumph too.
Priest has Deadpool more-or-less say this about Joe Kelly himself.
The Scrappy: Triumph came off this way to a lot of readers. He was supposed to.
Too Good to Last: Many of his projects, but especiallyThe Crew, which only lived through its first story arc. According to some, his entire career. He was only particularly active for roughly a decade, whereas most of his peers/contemporaries have, had, or will probably have 30+ year careers (Peter David, Tom Defalco, etc.) For a long time everybody just kind of assumed he'd come back sooner or later, and there were various rumors about him coming back to work for either Boom or Marvel, but he recently said on his blog that he has no interest in returning to comics.
Viewers are Morons: Part of his problem. A lot of his stuff was too high-concept/complex for the average comic book reader just looking for tights and fights.
