The Walking Dead fans and cast are equally excited about the season 6 finale that will feature the deadly villain — Negan. The finale episode is also expected to show a pretty brutal killing of a prominent character, so it's definitely going to be a bittersweet experience for TWD comic fans.

Actor Lennie James, who plays Morgan, is the recent addition to the list of cast members who can't stop praising the season 6 finale episode.

"Firstly, it is a phenomenal piece of writing," James told "Secondly, it is one of the greatest introductions of a character that I can remember in any television series, let alone in our television series. It's a phenomenal entrance. I don't want to build it up too much but it's probably too late now. It's amazing."

"For me, it was two things really. One was it was a sense of, 'Oh, my god. That's gonna be amazing.' Two was a desire to see it come to fruition and, from all intents and purposes and everything I know, it's fantastic. Jaws are gonna drop and people are gonna lose their shit, if you don't mind me saying. It's gonna blow some people's minds and break some people's hearts."

On the lines of "breaking some people's hearts," Carol actress Melissa McBride also had something to say about the upcoming finale...and it's not exactly good news. "It was so very dark," McBride said about the season six finale's script. "I couldn't say anything after I had finished reading it. I felt like I had dropped into a blackhole."

The Walking Dead season 6 finale episode airs 3 April at 9pm ET on AMC.
