Game of Thrones season six has a lot to live up to, especially after season five set an Emmy record and finally earned the show the top drama series award. But showrunners David Benioff and Dan Weiss are sure they’ve topped season five.

In an interview with Entertainment Weekly this week, Benioff said that he doesn’t think any of the 10 episodes are weak.

“Usually there’s an episode or two we’re kind of nervous about, that didn’t turn out as well as we hoped,” Benioff said. “This season there is not a weak episode.”

Benioff said that once the nearly finished versions of the episodes started coming in, their confidence rose.

“We’re always reluctant to say it’s ‘the best season yet’ because so much of that is in the eyes of the beholder,” Benioff told EW. “And Dan and I are so close to it that it’s impossible to be unbiased. But that’s my sense – watching them all together now, this is the best one we’ve done. It’s also the one I’m proudest of, because it was the hardest.”

The fifth season of Game of Thrones broke the Emmy record for most wins by a show’s single season with 12. Some of the big wins included Outstanding Drama Series, Outstanding Supporting Actor in a Drama for Peter Dinklage and Outstanding Writing for a Drama for Benioff and Weiss.

The sixth season debuts on April 24.
