So, "it just didn't make sense for us to have another season [of Community] at that level of audience," but with regards to Hannibal: "We still struggle to find an audience for it. It's great, we're keeping it going..."
Not to say that Hannibal should be cancelled (that is the exact opposite of what I want), and there's the fact that NBC only owned a portion of Community (with Hannibal being internationally co-financed), but if you're going to tell us that it made no sense to keep Community because of low ratings, then why are you also talking about how "great" Hannibal is, despite its ratings? The logic seems to be off, here.
Can Greenblatt just admit that he doesn't like/doesn't understand Community?
