they should make webisodes following individual zombies.
also, zombie cams for those trapped in cars or locked rooms. 6 years of one sitting there drying out.
They did a webisode series following the lady who became a zombie that Rick passes in like the pilot episode... I think she is like mostly eaten, dragging her torso around by her arms.
It wasn't very long, but actually had some cool content covering like the initial outbreak.... in the one bit someone goes and finds an entire family turned zombie and eating eachother in the basement and gets swarmed.
If they do more series, seriously they need to cover the actual outbreak and process of societal breakdown.... FTWD had that chance and completely blew it so they could jump over that part of the story more/less.
A new series following like 3-5 different distinct people or pairs or small groups (3-4) that starts before the outbreak and follows them as they navigate the outbreak and try to survive in various areas, perhaps with some subset surviving and eventually meeting, that could be cool.
Or a Black Mirror style TWD show that is just distinct 1 hr stories of various people and their experience at different times before/during/after the outbreak, that could also be good.
