Almost all novel and movie plots have to be unrealistic (even the โtrueโ ones) because the world is far more complex than can be portrayed on screen or in text.
Much (most) must be distilled, elided, eliminated, or condensed.
I am far more forgiving of โplot holesโ than most as they arenโt usually plot holes, really โ I just assume something happened off screen or off page that the work didnโt have time to show.
That doesnโt excuse bad plotting, though.
Really, though, reality is full of โplot holes.โ Why did WWI happen? Plot hole. Why did Germany invade Russia in WWII? Plot hole. Why did America elect George W. Bush twice? Plot hole. I could go on.
We are far more forgiving of the plot holes in reality than we are in fiction, for some reason. Perhaps because we have little choice.
