I'd vehemently disagree that 'it makes for a better story' is a legit excuse for having glaring contradictions in your story, and that's independent of the medium.
I'll be with everyone else defending a story when people overreact and call it a plothole when something that can be reasonably expected to happen isn't shown on screen or talked about (or on the page, in case of written media).
Like, I don't have to see the protagonist updating their friends on where they think the bad guys are in a story set in modern day to accept that these friends can show up just in time to save the day.
In short: Stuff happening off screen is not a plot hole, unless it explicitly contradics something that's been set up.
Maybe that's where the 'it makes for a better story' comes from? The better pacing you can get when not interrupting the story for phone calls to keep the cavalry up to date on where they'll have to show up in the end all the time.
What I can't excuse is when the story explicitly very clearly contradicts something that's been set up before.
Like, to stay with the example, it's established that there is no physical way for the friends to get to the scene only for them to show up anyway.
If you can't resolve your story without having physics breaking plot holes or pulling a deus ex machina, you need to get back and tweak the whole thing.
Also, if it's a plot twist, properly resolve the whole thing, don't just leave it there to look like a plot hole.
Or characters clearly acting out of character. I don't expect characters to act entirely logical, that would make a story boring as everyone would be a machine. But I expect characters to act in accordance with their established goals, world view, relationships and the information they have at the time.
If you need a character to act counter to their interests or in opposition to their side, at least put in the effort to set up that they have faulty information, instead of giving them a case of short term insanity (or even long term, if you want them to switch sides but don't actually put int he effort to make it believable).
Don't get me wrong, I can often overlook even bad plot holes when I'm having fun, but that doesn't mean that the story wouldn't be better if the creator put in the extra work to fix the plot hole(s).
I simply can't think of any legit plot hole that actually makes a story better, nor of any story that isn't made worse by having glaring plot holes in it.
