Game of Thrones has had its fair share of horrible and monstrous characters.
We've had murderers, rapists, plotters and manipulators. Joffrey, Walder Frey and Littlefinger to name just a few...
But according to the author of the books, George RR Martin, Breaking Bad's "Walter White is a bigger monster than anyone in Westeros."
And, as a writer famed for his monstrous creations, he's clearly not too happy about it. Writing on his blog after watching this week's episode of Breaking Bad, Martin added: "I need to do something about that."
The 64-year-old author is obviously a big fan of the hit AMC drama, calling its final season "amazing", so will we be seeing a character as evil as Walter arrive in the Seven Kingdoms soon?
Perhaps the Game of Thrones writer will be inspired by other elements of the dark drama, too. Before we know it Tywin Lannister could be organising the making of blue crystal meth in the Kings Landing dungeons...
Let's hope not, eh?
The final season of Breaking Bad is available in the UK on blinkbox, Netflix and iTunes.
