With Glass Onion: A Knives Out Mystery coming out, fans will be treated to another exciting whodunit. The first Benoit Blanc mystery found a way to subvert the expectations of the genre and keep audiences guessing right up until the ending when all is revealed.

A mystery movie has to deliver a satisfying answer to all the questions fans have been asking throughout the story. But fans on Reddit point to some examples of mystery movies where all the intrigue and suspense are ruined by a disappointing ending.

Frailty (2001)

The small indie mystery Frailty tells the story of a widowed father of two young boys who believes he is on a mission from God. He insists he can see evil spirits disguised as ordinary people and it is his responsibility to kill them, recruiting his sons to help him.

Redditor GoblinGregory finds the movie only works "until it tried to give a definitive answer at the end." Part of the thrill of the movie was deciding if this man was truly dispatching demons or if he was killing innocent people. Some fans would have preferred that the question remain unanswered which might have made the whole movie more powerful.

Now You See Me (2013)

While there are already plenty of rumors around Now You See Me 3, some fans might still be put off by how the first movie ended. It follows a group of magicians who pull off a series of seemingly impossible crimes with the help of their specific set of skills.

Redditor TalkAsSoftAsChalk finds the ending so damaging to the overall movie that it is "the only reason I don't rewatch it as much as I would like to." The main mystery that the audience wants answers to is how these crimes are carried out to look like magic. The explanation simply required too much suspension of disbelief for the audience especially as part of it suggests some magic is real.

Knowing (2009)

The mystery thriller Knowing sets up a very intriguing premise that some fans felt is let down by the end. It centers around the discovery of a document in a time capsule that lists deadly disasters of the past while also predicting massive casualty events that begin to come true.

It is an exciting premise that hooked one Redditor until it "introduces a very stupid element in that last portion of the movie." With such an intriguing idea, the answer to what is behind it is very important. Unfortunately, the revelation that aliens are warning humanity of their impending doom felt to many fans like an unfulfilling resolution.

North By Northwest (1959)

The classic North by Northwest remains one of Alfred Hitchcock's most rewatchable movies with a terrific mystery adventure filled with intrigue and excitement. The movie follows a man who is mistaken for a government agent and is subsequently hunted by foreign spies.

Despite the legendary status of the filmmaker, Redditor bob1689321 insists that "Hitchcock does generally have a problem with endings, but that's probably his worst." It seems to be the final image that throws viewers as the two main characters get romantic on a train before cutting to the train going into a tunnel. It is a silly and unsubtle gag that might feel more suited for an Austin Powers movie.

Gone Baby Gone (2007)

The Boston-set mystery Gone Baby Gone tells a dark tale of moral complexities. It follows young private detective Patrick Kenzie who is hired to find a young girl who was seemingly taken from her mother's home.

One Redditor says that Gone Baby Gone was a perfect movie with a "terrible decision at the end" as Patrick returns the girl to her troubled mother rather than allow her to stay with the people who insisted they were trying to save her. Some fans clearly blamed the movie for Patrick's choice, even if the movie suggests he might have been wrong.

Unbreakable (2000)

Though perhaps not his most widely known movie, Unbreakable remains one of M. Night Shyamalan's best movies. The story centers around David Dunn, the sole survivor of a train crash who is given a new purpose upon meeting Elijah Price, a man who suggests David is a superhero.

Redditor Unfair-Load5760 finds that the disappointment in the end is "basically just the final titles" that come after a terrific Shyamalan twist. David discovers that Elijah caused the train crash in his search for a superhero. Unfortunately, the stunning revelation is followed by a title card explaining that Elijah was arrested which seems to have had a deflating effect on what might have been a stunning ending.

Deja Vu (2006)

Deja Vu starts with a terrorist bombing onboard a ferry then follows Agent Doug Carlin's investigation into what happened and who the bomber was. He is introduced to tech that allows him to look into the past and decides to use it to prevent the attack from happening in the first place.

The movie gets really exciting once Carlin goes back in time and the audience starts to see how some of his actions affected the original timeline. However, Redditor Dead_Parrot explains that Carlin sacrifices himself to save the day only for him to be alive in the original timeline "making the majority of the movie pointless."

Enemy (2013)

In one of Denis Villeneuve's lesser-known movies, Enemy follows Adam, a married professor who discovers that there is a doppleganger of him who he becomes obsessed with. The mystery of the movie sees the lives of these two seemingly identical men colliding and the damage it has on their relationships.

Redditor dgiszewski claims they were "totally invested then the ending came and it s*** the bed." It is certainly a perplexing ending as Adam enters his bedroom to find his wife has turned into a giant spider. While some fans enjoy such endings where they have to explore what the filmmaker is saying, others can find it to be a frustrating way to end things.

The Batman (2022)

Fans were thrilled to see The Batman embrace the character's detective origins and making the movie a dark mystery. It explores Batman's race to stop The Riddler as he carries out a series of deadly attacks against some of Gotham's most powerful citizens.

Redditor ChemistryRespecter finds a number of issues with the ending, from the forced action climax to Riddler's cliché motivations to the scene "with him meeting yet another Joker." While The Batman breaks many rules in this tale of the Caped Crusader, some fans might have been disappointed with a finale that seems like it could have been from any other Batman movie.

The Village (2004)

Though M. Night Shyamalan has delivered some truly epic twists in his movies, The Village is somewhat infamous for the filmmaker perhaps trying to be too obsessed with trying to fool audiences. The movie is set in a community of farmers and pilgrims who live in fear of the dangerous creatures hiding in the surrounding forest.

Redditor s_360 claims that, early on in the movie, they "guessed what was going on and dismissed it as ridiculous." The revelation that the movie takes place in an isolated society in modern days just didn't work with audiences. For a mystery to have an ending that fans can guess can be just as damaging as an ending they can laugh at. Unfortunately, The Village manages both.
