George R.R. Martin is no stranger to bad guys, given that he’s created some pretty despicable characters in the fictional world of Westeros. But, when it comes to the fictional world of superheroes, the author has a bit of beef with the way Marvel portrays its villains.

“I am tired of this Marvel movie trope where the bad guy has the same powers as the hero,” Martin wrote in his blog. “The Hulk fought the Abomination, who is just a bad Hulk. Spider-Man fights Venom, who is just a bad Spider-Man. Iron Man fights Ironmonger, a bad Iron Man. Yawn. I want more films where the hero and the villain have wildly different powers. That makes the action much more interesting.”

Martin’s comment came about while writing a review of Ant-Man, which the author otherwise seemed to enjoy. He referenced his history as a self-professed Marvel fanboy, as well as his worry about if the film would do justice to the characters’ comic legacy. “I am relieved and delighted to report that they did it right,” Martin added. Maybe there’s not enough family drama and power struggle in the Marvel universe for Martin’s liking? Or maybe he’s just waiting for the ultimate “baddie” to make his debut in a few years, when Thanos comes to wreak havoc on our heroes.
