i tried typing up a serious response to this topic but there's no point, really - this topic is inherently flawed. you watched the show once and didn't care for it; that's fine. no one is forcing you to like the show. but that 20 minutes of experience with the show doesn't mean you can make grandiose statements like "[Dan Harmon] doesn't understand how sitcoms work" or make anecdotal statements about how no one you know talks about Community so 'shut up, internet' and have those statements actually mean anything.
this is the internet. you choose what you're exposed to. if you're tired of hearing about community, there are steps you can take to avoid it. making a topic about community on a message board that enjoys community is not one of those steps.
