You have 36 seasons, about 30+ plus Treehouse of Horror Halloween specials, and one full-length feature movie to catch up on. That's a significantly tall task to execute plus quite a few fans of the show who are in their late 40's/early 50's right now werent even in HS or college when the sitcom first starting airing full-time in 1989 and not as a crudely-designed, hard-to-follow short animated series that aired during the Tracey Ullman Show on Fox in the summer of 1987.
