According to IMDB, while "One Terrible Day" was the fourth Our Gang comedy, it was the first one shown....meaning they most likely thought it was the best of these early comedies.
When the story begins, the snooty Mrs. Pennington Van Renssalaer decides to put on a picnic for the local children...not out of the goodness of her heart but as a publicity stunt. She is hoping to impress all her snobby friends by demonstrating (with LOTS of photos and publicity) her love of children. Unfortunately, she chooses the Our Gang kids...who bring along their pet dog and monkey and pretty much make nuisances of themselves.
Most everyone enjoys seeing snooty people getting their comeuppance...particularly when they are using poor kids in order to make themselves look charitable and kind. This and some nice, gentle laughs make this one an enjoyable film...worth seeing and often clever.
By the way, in the early Our Gang comedies, Farina's gender swaps a lot. In this one, everyone says he's a girl...whereas in others he plays a boy. Either way, at least when he got a bit older they stuck to one and not both!
