In its original American broadcast, "When Flanders Failed" finished 29th in the ratings for the week of September 30 – October 6, 1991, with a
Nielsen rating of 13.9, equivalent to approximately 12.8 million viewing households. It was the highest-rated show on Fox that week. Since airing, the episode has received mostly positive reviews from television critics. Kirk Baird of the
Las Vegas Sun named it the fifth best episode of
The Simpsons, and
Central Michigan Life called it an "instant classic". Pete Oliva of
North Texas Daily said the episode "proves that it is possible to laugh and cry at the same time without being able to control either response". Bill Gibron of DVD Verdict said "When Flanders Failed" shows that even if
The Simpsons is not dealing with famous celebrities or "high profile places", the writers can still "wring uproarious comedy out of their cast of regulars. Flanders is a special creation in the canon of humor, a regular guy who is funny because of how hyper-normal he is compared to his Neanderthal neighbors. The focus on people who are left-handed, and the whole idea of being a lefty, is an unusual basis for a television show. But then again, nothing about
The Simpsons is ever common." Hock Guan Teh of DVD Town also praised the writers, saying they "are able to craft a downtrodden tale for the perpetually clueless Flanders family that serves to illustrate how dark emotions can eventually be overcome by Homer's guilt. A memorable episode." Niel Harvey of
The Roanoke Times called "When Flanders Failed" a "classic bit of Simpsonia". The episode's reference to ''It's a Wonderful Life
was named the 26th greatest film reference in the history of the show by Total Film'''s Nathan Ditum. Nate Meyers of Digitally Obsessed rated the episode a (of 5) and commented that "perhaps it is not profound in its examination of jealousy causing people to behave irrationally, but it handles the topic in a serious manner while not compromising the show's humor. The side story with Bart stems from
the era of the series when Bart was the big star, but it still has some funny bits." DVD Movie Guide's Colin Jacobson wrote: "Mean Homer equals Funny Homer, so 'When Flanders Failed' presents an above average show. He seems unusually crude here, which makes him amusing. The subplot with Bart and his karate class also adds good material, especially when he threatens to turn the 'Touch of Death' on Lisa. Another sappy finish slightly mars this one, but it remains generally solid." Kimberly Potts of
AOL named it tenth best episode of the show and commented: "Schadenfreude is the theme of this tight episode about Homer's joy at the failure of Flanders' Leftorium store. There are few times Homer is more shamelessly smug than he was while imitating Flanders and using Ned's yard sale grill, and we haven't even mentioned Bart's 'Touch of Death' subplot."
Winston-Salem Journal's Tim Clodfelter called it an "outstanding" episode. ==References==
