The Walking Dead: 10 Most Improved Characters In 2015

8. Glenn

Mid-season 5: Glenn has always been a big character though the hype mainly surrounded the likes of Rick, Carol, and Daryl at the time. Mid-season 6: His 'death' scene brought legions of fans out to declare their love for Glenn and anger at the writers for apparently finishing him off. His return will be huge for the group. Glenn is one of the longest serving members in the entire show and because of that, he now seems like part of the furniture. He's performed some incredibly important duties in the series, but by Season 5, he could blend into the background as new characters were poured in. His major storyline in Season 6 re-outlined his significance to the group and generally made us all appreciate how brilliant Glenn actually is.
