AMC's The Walking Dead portrays a ragtag band of survivors in the midst of a zombie apocalypse. As with most TV shows, it features a diverse cast, with almost all major ethnic groups being represented. The show depicts black people in a very particular way. T-Dog, Oscar, and Tyreese are all physically strong and of average intelligence. In Season 3, T-Dog, Oscar, and Tyreese are each inducted into the group, but there is no overlap. Although not an ideology, this perpetuates the Hollywood trend of "the black guy always dies first." Glen is asian. He is very bright, but physically weak (compared to the other characters) and hopelessly awkward. He fits the bill of the asian, testosterone-starved, math nerd.
Perhaps the most obvious stereotypical characters are Daryl and Merle Dixon, hailing from the deep south. Merle's troubled character is the embodiment of everything negative about the South and rednecks. He is racist, sexist, and addicted to meth. He is thick-headed, and mercilessly aggressive. Daryl, though, is the opposite. He represents everything positive about the South and rednecks. Daryl is the only character who was even slightly prepared for the zombie apocalypse. He is a highly skilled outdoorsman and hunter who never backs down from a challenge. He always seems to be coming to somebody's rescue. The Walking Dead embodies of the stereotypes that impede our culture's progress.
