Community is one of the greatest comedy shows of the 21st Century. Showrunner Dan Harmon crafted a unique vision of college life with the idiosyncratic community college Greendale, and over the course of six seasons produced many fun experimental episodes. One of the most forward-thinking, optimistic modern sitcoms, Community was whip smart with its constant pop culture references, homages to other media, and Harmon’s famous “story circle” structure.
