AMC’s The Walking Dead - starring Andrew Lincoln - has been renewed for a further season, meaning there will be at least one more to look forward to. The mid-season finale of the zombie thriller didn’t disappoint in terms of ratings, much like the previous episodes before it. The studio has also announced that showrunner Glen Mazzara is to leave the show

Here's the statement:

“Today, AMC announces the season 4 pick-up of The Walking Dead. 

AMC also jointly announces with Glen Mazzara today that for future seasons, the two parties have mutually decided to part ways.  Glen guided the series creatively for seasons 2 and 3.  AMC is grateful for his hard work.  We are both proud of our shared success. 

Both parties acknowledge that there is a difference of opinion about where the show should go moving forward, and conclude that it is best to part ways.  This decision is amicable and Glen will remain on for post-production on season 3B as showrunner and executive producer.”

Walking dead hasn't only enjoyed success on a commercial level, but on a critical level too, with every season so far scoring over 80/100 on metacritic. It has also won 11 awards out of 46 nominations, including Emmys, Golden Globes and Saturn Awards.
