Adam Serwer nit picks AMC's The Walking Dead:
What was great about Kirkman's comic [upon which the TV series is based] is its relative lack of sentiment, its willingness to allow even its most compelling characters to meet gruesome ends while crushing the survivors under the weight of incomprehensible suffering in the face of a bleak, hopeless future. You turn the page because you can't believe the people who are still alive are actually making it, and because you can't wait to see the people they must become in order to do so. The Walking Dead is fundamentally a tragedy about how people become inhuman in order to survive, and for that to work, you need some characters who actually resemble human beings.
Scott Meslow also advocates for more character development.
