HBO’s "Game of Thrones" is known for its ruthless characters, but the writer of the original book series, George R.R. Martin, took to his blog to complain that Walter White on AMC’s "Breaking Bad" is "a bigger monster than anyone in Westeros."

"I need to do something about that," Martin added.

Martin wrote his thoughts about "Breaking Bad" on his blog after watching the "Ozymandias" episode, which caused some stunned reactions from viewers after several characters died, reports the Los Angeles Times’ Show Tracker.

After sharing his thoughts about White’s character, Martin said he believes "Game of Thrones" has a chance at beating "Breaking Bad" for this year’s Emmys — adding: "(only a shot, though, I think they are the clear favorite), which pits us against their previous season … but there’s no way in hell that anyone is going to defeat BREAKING BAD next year, when their last season is the one in contention."
