The Walking Dead delivered some brutal blows to the characters of Robert Kirkmans creation, but none could compare with that of Glenn at the hands of Negan. While the death scene for the popular character was inevitable in the TV adaptation considering its pivotal inclusion in Kirkmans comics, when it arrived, it caused a whole new wave of controversy. For star Andrew Lincoln, who plays Rick Grimes in the zombie horror franchise, it was perhaps the point that the series pushed things a little bit too far.
