The A.V. Club has an interesting, and likely debate-provoking, list of "21 artists who changed mainstream comics (for better or worse)."

As the title suggests, the panelists don't have kinds words for everyone. They heap praise on the likes of Jack Kirby, Steve Ditko and Carl Barks, and mix in some mild criticisms with their assessments of George Perez and Jim Lee.

But for George Tuska, Rob Liefeld, Greg Land and Alex Ross, they get a little rough.

Of Ross they write, "He’s a pioneer of the dull, unimaginative craze for giving superheroes celebrity faces, and with his shaky layouts and mediocre visual storytelling." The charges against Land and Liefeld are, by now, quite familiar.

And then there's "poor George Tuska," who's described as "the King Of The Fill-In Issue, hopping in to provide bland, forgettable work whenever someone else blew a deadline."

So, what do you think? Are their assessments fair?
