“Don’t let the incomprehensibly adorable little corgi who supplies “Cheddar” with its title fool you: this week, Brooklyn Nine-Nine is about something more substantial than cute puppies doing cute things, even though it is mostly about that. “Cheddar” is for the most part a fluff episode (no pun intended, though Cheddar is pretty fluffy), a charming one-off built around a single joke that it carries out to the best payoff possible. It’s really only when we get to that payoff that we see that there is more to “Cheddar,” and that there has been the entire time.” (Via Paste Magazine.)
