r/Flintstones

Why does the first episode of the Flintstones the Flintstone Flyer not have a happy ending instead it has a bad/downer ending shouldn't cartoons first episodes normally have a good/happy ending instead it ends with Wilma and Betty going on the warpath after learning their husbands tricked them in order to go bowling instead of the opera with them, thanks to Barney's stupidity. Fred and Barney manage to escape on the Flintstone Flyer, but Barney is running out of steam and the wives are waiting for them below why doesn't it have a happy ending shouldn't first episodes of cartoons normally have a happy ending and isn't it too early for a bad/downer ending?

Since Fred and Barney lied to Wilma and Betty to get out of the opera by Fred pretending to be sick and going out bowling and they were treated shabbily in this episode and Fred and Barney using the Flintstone Flyer to get away from them do you root for Wilma and Betty in this episode and are they heroes in this episode?
