Glass Is Full Of Unanswered Questions & Plot Holes

Sarah Paulson and Samuel L Jackson in Glass

Warning: SPOILERS for Glass.

M. Night Shyamalan's Glass leaves behind a ton of questions - and flat-out plot holes - regarding the logic of its story and the behavior of the characters. The third film in the director's unofficially named Eastrail 177 trilogy unites David Dunn (Bruce Willis) and Elijah Price/Mr. Glass (Samuel L. Jackson), the hero and villain of Unbreakable, with Kevin Wendell Crumb aka the Horde (James McAvoy), the villain of Split, into a shared comic book-inspired universe.

Unbreakable was released in 2000 at a time when the director was at the height of his popularity. After several years of cinematic failures, Shyamalan began to mount a comeback that culminated in 2017's Split. That well-received and financially successful horror film, which also starred Anya Taylor-Joy as kidnap victim Casey Cooke, ended with a shocking reveal that David Dunn and Mr. Glass exist in the same universe. The stage was set for Shyamalan to tie Unbreakable and Split together in Glass, the third film of a trilogy that no one realized was a trilogy, which was ostensibly 19 years in the making.

Ultimately, Glass is an ambitious but very strange beast of a film. Shyamalan makes a series of creative decisions that fans are finding themselves baffled by. Glass will likely be debated about for years to come but, right now, here are the biggest questions we have about the film and its many odd contrivances and plot holes.

David Dunn's Vulnerability To Water Now Makes No Sense

David Dunn Dies in Glass

After he's institutionalized at Raven Hill Memorial Hospital in Glass, David is placed in a room built to exploit his weakness to water. As Dr. Ellie Staple (Sarah Paulson) explained, multiple jets attached to a massive water tank outside would spray David with water if he got aggressively violent or tried for the door. David was compliant at first but after he saw Kevin Crumb was being held across the hall from him, he began to get desperate to escape and he got sprayed by water, rendering him powerless.

But why would what was essentially taking a violent shower make David helpless? In Unbreakable, David's vulnerability wasn't water but drowning; it was inferred that because his bones and muscles were denser than normal, which explained his strength and resistance to injury, he had a harder time swimming or even floating. But now exposure to water saps his strength entirely? How does David shower or bathe? Glass draws a connection that David's vulnerability is psychological and related to an incident when classmates nearly drowned him in a swimming pool as a child, but this seems like a weird retcon of David's weakness to water.

Why Didn't Kevin Just Close His Eyes To Avoid The Strobe Lights?

Glass Movie James McAvoy

To keep the Horde from bringing forth the Beast (and allow Dr. Staple to meet all of Kevin's personalities as well as give James McAvoy the opportunity to showcase his acting), strobe lights were installed in Kevin's room. Every time he tried for the door, the lights would burst and force Kevin to switch to a different personality. It worked every time and Kevin couldn't escape.

Yet not a single one of Kevin's 24 personalities, with their varying levels of intelligence and cunning, ever thought to just close Kevin's eyes to avoid the strobe lights. Neither the diabolical Patricia, the serious-minded Dennis, nor even the childlike Hedwig figured out the simplest and most obvious solution to beat this boobytrap. They could have called forth the Beast and he could have climbed the walls and ceiling over the strobe lights even with his eyes shut.

Could David Dunn Really Have Operated As The Overseer Undetected For 19 Years?

Bruce Willis in Unbreakable

In the 19 years since Unbreakable ended, David continued his activities as a superhero and gained a few codenames like the Green Guard, the Tip-Toe Man, and the Overseer. Glass points out that the Overseer's image was recently captured on security cameras and that the police are always hunting him, which makes it hard to believe that he was able to be a vigilante and evade capture for 19 years, especially with how easily he and the Beast were caught when they fought in the warehouse. David did have his son Joseph (Spencer Treat Clark) as his Man in the Chair, but Dunn's security company looks like a relatively new operation; before that was set up, how did David escape capture for so long, especially in Shyamalan's more grounded and realistic world? After all, he's just an aging man in a rain poncho; he doesn't have all of the resources and training as a ninja-like Batman does.

The Way David Finds Kevin Is Random And Too Convenient

How David and Joseph locate Kevin Crumb and the kidnapped girls also seems to rely on sheer luck more than anything else. Joseph tracked the murders caused by the Horde, which for some reason forms a convenient triangle in Philadelphia. Then Joseph (almost arbitrarily) decides Kevin must be in an industrial area east of the triangle. It's also lucky that the Dunns' security company seems to have no clients and frees David to take long walks to try to sense Kevin. But David's strategy to locate his prey is to literally just bump into as many people as he can on the street until he runs into Kevin - which he conveniently does!
