There are many types of movies with unexplained parts. We often do not see a complete explanation in a suspense or mystery. M. Night Shyamalan doesn’t necessarily worry about the giant plot hole in The Sixth Sense, because he trusts that audiences will be able to suspend their disbelief, and accept the film's amazing twist ending. I mean, it is a film about a little boy who is able to see dead people, so we’re already being asked to buy into the dream world of the film.
Then, there are those pesky MacGuffins - these narrative devices are used to incite a plot point, but are then never referenced again in the story. Think about the glowing briefcase from Pulp Fiction. Do we ever find out what's inside? No, it’s a MacGuffin; it doesn’t matter. That is, it doesn’t matter if you’re one of those types of people who watch movies that don't explain big parts.
So whether the items on this list are plot holes, MacGuffins, or simply just films with unexplained moments, most of these stories thrive without tying up every loose end. Of course, some films on this list could use a little exposition or narrative tightening. Be sure to vote up the films that are actually better off not explaining every detail, and vote down the films where an explanation would improve the story.
Trying to explain all the various plot hole issues that arise in film about time travel can be exhausting. But this one from Back to the Future cannot be totally ignored. Marty McFly (Michael J. Fox) goes back in time and befriends both of his parents in an effort to make sure they fall in love. But then they don't remember him? Is there no point after Marty is born and grows up, where Mr. and Mrs. McFly say to each other, "My, our boy looks exactly like that Calvin Klein we met when we were in high school, who suddenly disappeared."

M. Night Shyamalan's first big movie features one of the best plot twists in film history.
Dr. Crowe (Bruce Willis) is dead the whole time and doesn't know it. But that doesn't make much sense. How could Crowe go about his day as a psychologist and a person just living his life and not realize that no one is interacting with him? It's a giant plot hole for sure, but does that really matter?

Vincent Vega (John Travolta) and Jules Winnfield (Samuel L. Jackson) go through a lot of trouble, and almost die, in order to retrieve a briefcase for their gangster boss Marsellus Wallace (Ving Rhames.) At one point, Vega opens the briefcase to a clear glow. We see this glow again during the diner scene robbery.
What is inside the case? We never find out. There are a thousand theories to this famous Pulp Fiction mystery, including that it's Wallace's soul. However, it's more likely that the briefcase is simply a MacGuffin, a narrative device used to start a plot line, but then is never referenced again, because it is ultimately irrelevant to the outcome of the story.
