Keeping up with the pace is often difficult for people who are writing for the show. They sometimes have a difficult time making the show different while at the same time keeping the show’s premise. Some people may get bored after listening and watching the show’s same events happen over and over again. Based on the reviews of each season, it seems that the best season for The Walking Dead was its first season.
However, its worst seasons have been near the middle end of the seasons. Season nine seemed to turn it around, but the first several seasons were considered the best. The seasons in the middle and after seem to be what is wrong with the series. Hopefully, the next season will be outstanding.
