Rick and Maggie's exit

We all know that the show will never be the same when Rick Grimes (Andrew Lincoln) and Maggie Greene (Lauren Cohan) leave the show. Rick's departure from the series, be it open-ended or via death, is going to leave a void which will be impossible to fill. Because Daryl doesn't exist in the comics and Carol died way back in the series, the comics mainly focus on these two characters. We'll just have to see how good (or bad) does the show do when they depart from it.
