Comic book writer Robert Kirkman's "The Walking Dead" adaptation turned out to be one of the most successful TV shows on AMC. However, he has one regret. The network is currently showcasing Season 5 of "The Walking Dead."

Robert Kirkman talked to The Hollywood Reporter about his major regret. He stated that he shouldn't have done the CDC instalment at the end of "The Walking Dead" Season 1. In this episode, Edwin Jenner tells Rick Grimes that everyone is infected.

He said that they revealed it at a very early stage. "It possibly gave away too much information and was such a big change very early on in the series," Kirkman stated. He admitted that Season 1 should have ended in a different way.

"It ended up being a fun episode. I love the character of Dr. Jenner and thought Noah did an amazing job. But there were things in that episode that I think seem very much not of The Walking Dead world."

Kirkman had another problem with the episode. According to Kirkman, that Jenner had been researching on the subject and still did not find a cure. He has been careful in the comic book series.

"I've been careful in the comic series to not say what's happening in other parts of the world. It's something that's going to be fun to explore in the spinoff series. But the fact that France is mentioned in that episode and other things like that, I probably would have steered away from that stuff if I had to do it all over again."

Despite the reveal at an early stage, "The Walking Dead" has managed to stay at the top. Season 5 of the show is currently approaching its midseason finale.
