“ And it wasn’t just that Leslie won — and Amy Poehler’s face as Leslie absorbs the news is among the best pieces of acting she’s ever done on the show — but that beautiful acceptance speech she gives. We start off with Ben’s perfectly well-written remarks, but then Leslie runs out of his words and starts improvising her own and they’re even more eloquent and perfect and moving. That is why all these people went to the mattresses for her, and that is why we watch “Parks and Rec,” on top of it being insanely funny. I watch too many other TV series (including a much-hyped show on this network whose title rhymes with “rash”) who spend a lot of time telling you why certain characters are awesome, then fail to adequately show you. With Leslie, “Parks” shows you, again and again and again. I didn’t think Leslie’s closing statement from “The Debate” could be topped as an emotional moment for her, but I think this one did.
