Game of Thrones doesn't have a difficult time redirecting attention to new characters and making them interesting. We know some new big players are coming in and I wouldn't mind seeing one or two long timers offed so the new guys can get their due. Kill Daryl and Glenn and put
Jesus and Negan in the spotlight. It raises the stakes and keeps things fresh and suspenseful. I suspect Negan is going to be very fleshed out based on the Governor having gotten his own episodes. The thing is we go several episodes at a time without seeing some lower level characters right now so when they kill them there's not really an impact. Can anyone say they cared about Denise being killed? Sure it was out of left field so it was a little shocking but I didn't feel the show lost anything.
