Another clear evidence of the utter lack of imagination of the writers is the fact that there have been shows with a lot better dialogue and logic that happened in a prison (Oz, HBO), a small town (Twin Peaks, Deadwood etc.) or a theme park (Westworld). TWD writers have the whole world at their disposal, other continents, cities, towns, people, political angles, interpersonal angles, hunger, jealousy, envy, reproduction etc. to explore. Then, there is this whole science angle, why it did happen, what is the cure etc. This season, none of that has been explored. It's moving at a very slow pace.
To compare, a show like Oz had 5-10 interesting characters and storylines inside 5 rooms. It was all about writing.
