Reedus – who plays Daryl Dixon in the show – has said that the new episodes will make up for the frustration.

“Trust me,” he said. “I think probably the planet is going to explode. That’s my feeling. It’s so good. Every time we go on a promotional tour talking about what’s going to come, we all say ‘Oh my God, it’s amazing. I can’t wait for you to see it.’ But it continually surprises me how this show grows and is put together and the execution of it – no pun intended.”

He went on to add: “It blows my mind. It just continually reaches a new plateau every single time, and this is the highest plateau we’ve ever been. So just wait. It’s worth the wait, trust me.”
