At Guilford College in Greensboro, NC, several first-year writing instructors use season four of The Wire as the major text when we teach ENG 102: College Reading & Writing.
The students love it, of course, and it is exhilarating to discuss the episodes & storylines with them. They get so into scene-by-scene "close readings," and their analyses of how various social institutions intersect/connect are sharp & engaged.
I teach s4 alongside Freire's famous Pedagogy of the Oppressed ch. 2, and with Sir Ken Robinson's TED talk about how schools kill creativity. Our rhetoric text is "They Say/I Say: Moves that Matter in Academic Writing" by Graff & Birkenstein. This is the most fun I've had teaching first year writing in awhile!
