Written by Daniel J. Goor and directed by Dean Holland, the episode marked the culmination of a seven-episode story arc about the harvest festival that began with the third-season premiere, "Go Big or Go Home".
With the Harvest Festival days away, Leslie surprises everyone by booking Li'l Sebastian, a miniature horse and legendary Pawnee celebrity.
As Leslie reassures the reporters there is no curse, the power generator blows out, leaving the festival dark and stranding most of the parks department on a Ferris wheel.
The episode marked the culmination of a seven-episode story arc that began with the third season premiere, "Go Big or Go Home", in which Leslie and the parks department prepare to relaunch the harvest festival, which had previously been a Pawnee tradition before it ended.
[10] The episode was filmed out of sequence from the rest of the season so the weather would be cooler when the scenes were shot; Schur jokingly said if this was not done, "the week that we would have been shooting it was like 148 degrees here and the actors would be dead now".
Afterward, the reporters were taken to the set of Parks and Recreation where they were able to greet and pose for photos with the actual miniature horse who played Li'l Sebastian.
[10][12] When Ben fails to understand the appeal of Li'l Sebastian, Ron explains the miniature horse has an honorary degree from the University of Notre Dame, a school in Indiana, the state where Parks and Recreation series is set.
Ann claims that, while distraught from her breakup with Chris, she bought $700-worth of candles from Anthropologie, a retail store that sells women's apparel and home accessories.
[4][14] "American Girl", a song by the rock band Tom Petty and the Heartbreakers, plays during one scene showing an overview of the harvest festival.
New York magazine writer Steve Kandell called it the most pivotal episode of the season in terms of "resolving and resetting narrative stakes", as well as the most complex from a production perspective.
[19] Kandell wrote, "There's something that feels particularly satisfying about watching a wholly sympathetic, albeit fictional, character like Leslie Knope do well by her own ambition and by her friends.
"[3] Entertainment Weekly writer Ken Tucker said the episode placed Parks and Recreation "squarely in the tradition of great gentle-hearted sitcoms" that treated its characters "with equal affection, and has relatively little patience for irony and cool detachment".
He praised Amy Poehler's performance, and enjoyed how the characters' excitement over Li'l Sebastian demonstrated how "in some parts of this great land, there are people who aren’t jaded, who are open to wonderment, who find vessels in which to pour their joy".
[4] TV Squad television reviewer Maureen Ryan called "Harvest Festival" a "delightful, comedically deft episode, one that depicts the mildly demented world of Pawnee in loving detail".
[12] Joel Keller, also of TV Squad, called it one of the best episodes of the season, and that it provided each member of the ensemble cast moments to shine.
[15] James Poniewozik of Time magazine called it a "splendid" episode that "combined slapstick, authentic stakes and a holistic picture of the oddball history and commonalities that bond the folks we've come to know in Pawnee".
[21] Punchline Magazine writer Megan Gilbert said the episode featured "plenty of laugh-out-loud moments" and particularly enjoyed the "sweet non-aggressive fighting" between April and Andy.
[14] TV Guide writer Damian Holbrook said the difficulties that plague the harvest festival were funny, "but like the best of Parks, these hiccups are matched with acres of heart".
[7] Alex Strachan of the Montreal Gazette praised the show for being funny without resorting to cynicism or cruel jokes, and called the series "one of the sharpest, smartest comedies on TV at the moment".
[6] Hollywood.com writer Eric Sundermann enjoyed the new direction Ann's character was taking, as well as how "Harvest Festival" accurately portrays small-town life.
Club called the episode "celebration of the whackjobs that live in Pawnee and how their singular focus can make for some adorably naive comedy".
However, he said it was "chock full of dozens of little moments that make the entire episode worthwhile", and particularly praised the Native American curse and the parody of the media.
