Movies and shows with ambiguous endings or confusing plots

There is a certain subset of films and television series defined by their refusal to provide a clean resolution—stories where the ending remains murky and open to interpretation. We find ourselves constantly debating who actually pulled the trigger, who survived the final act, or whether we were witnessing reality or merely a fever dream. Even decades later, these narratives spark endless debates, with one camp championing one theory while another clings to its own version of the truth. Here are a few notable examples:
1. Total Recall (1990)—to this day, people are still arguing over whether everything Quaid experienced was real or just a sophisticated hallucination.
2. The Sopranos—that final cut to black leaves us wondering if Tony actually made it out of the diner or if his journey ended right there.
3. Memento—the true motives behind the murder of the protagonist's wife remain shrouded in ambiguity.
4. True Detective—there are plenty of threads left dangling and mysteries left unsolved in that gritty landscape.
5. Prometheus / Alien: Covenant😁—these entries leave a significant amount of lore unexplained, inviting constant speculation.
6. Lost—where do you even begin with that one?😁
7. The filmography of David Lynch—now those are in a league of their own entirely.

Of course, the list goes on indefinitely. Which ambiguous endings have stayed with you the most?

I don't see how there's any confusion regarding Soprano.
Lost has been explained a thousand times over.

Prometheus and Alien: Covenant are just one (two 😁) massive messes.

Memento leaves you knowing exactly who did what and why.

I feel like with Nolan, the real head-scratcher is whether it was a dream or reality in Inception.

My favorite ambiguous endings have to be Dice and The Man from Earth.

Picnic at Hanging Rock, if we're counting that one.

Timecrimes would probably be my top pick; honestly, a lot of movies dealing with time paradoxes tend to get a little confusing.

Lynch...with an emphasis on "Mulholland Drive"

Ryan Wilson2 said:Lynch... specifically when you look at Mulholland Drive

To me, the plot in Mulholland Drive is actually pretty straightforward.

I’m a sucker for movies that actually make you use your brain... some of my absolute favorites are

2001: A Space Odyssey
Mulholland Drive
Persona
Predestination
Inland Empire
Donnie Darko
Eraserhead

I mean, it’s obvious the whole thing is just one big critique of Hollywood...

That’s just one layer of it, though. I don't think that's really the core plot or the main driving force.

Not really. I think the whole point of MD is actually the critique of Hollywood itself. The dream vs. reality thing? That’s just the vehicle they're using to get there, not the end goal...

Nope.

I mean, you really only need to look at the opening credits to see what's up. They list Justin Theroux (the guy who played the director Adam) before they even get to Naomi Watts. It's pretty obvious right from the jump who the story is actually centering on...

The ending of Inception is pretty ambiguous, though isn't it true that Nolan basically suggested the main guy just decided he didn't care which level of reality he was in, as long as he was happy and back with his kids...

dustycanyon5 said:It’s pretty telling if you just look at the opening credits. You see Justin Theroux—the guy playing the director Adam—listed before Naomi Watts. That kind of tells you right away who actually carries more weight in the story.

If you honestly think Theroux's character holds more importance than Naomi Watts' role in MD, then you might have missed what was actually happening on screen.

Lost was explained plenty of times already.

Ajutoi will clear everything up for you.

vivideagle7 said:The plot in Sunset Boulevard is perfectly straightforward.

Well, that’s subjective, isn't it? I don't think it's possible to describe a film in one singular way that satisfies everyone who watches it.

For instance, I find the narrative of Lost to be completely lucid, yet I know plenty of people who struggle to make sense of it at all.

vivideagle7 said:If you actually think Theroux’s character carries more weight in MD than Naomi Watts’ role, then you definitely missed the point of the movie.

Look, I’ve sat through MD at least 20 times now—no exaggeration—so I pretty much know this flick inside and out...

Ryan Wilson2 said:For me, Lost is perfectly clear—it just depends on how you look at it.

Look, could you maybe walk me through it? (Feel free to shoot me a DM if that's easier), or even just drop a link somewhere that breaks it all down. I’ve got a mountain of unanswered questions floating around my head—I started watching this way after everyone else had already finished it. 😁
