Iron Lung Movie Reviews: A Divide Between Fans and Critics
The critical reception of the film has been a textbook example of the “Rotten Tomatoes Gap.” While critics found the experience punishing and slow, audiences—largely Markiplier’s 38-million-strong “loyalists”—hailed it as a cinematic triumph of atmosphere.
The Critical Consensus (50% Tomatometer)
Professional critics have been largely divided. The primary complaints center on:
- The Runtime: At 127 minutes, many reviewers felt the film was “bloated.” Critics like Nate Richard (Collider) noted that while the dread is effective, the pacing bogs down in the second act.
- The Script: Several reviews pointed out that a game designed for a 30-minute playthrough struggled to sustain a two-hour narrative.
- Accessibility: For those unfamiliar with the “Quiet Rapture” lore or David Szymanski’s original game, the film felt “alienating” and “confusing.”
The Audience Reaction (89% Popcornmeter)
Conversely, fans have championed the film for its:
- Immersion: The use of 80,000 gallons of fake blood and a single-location set created a suffocating, claustrophobic experience that felt “authentic” to the source material.
- Acting: Markiplier (Mark Fischbach) has been praised for a “surprisingly fantastic” and understated performance, successfully shedding his high-energy YouTube persona.
- Sound Design: Many viewers noted that the audio—heavy on creaking metal and sonar pings—was the “true monster” of the movie.
Why Was It Removed From the Charts?
Early on Monday, February 2, a controversy erupted when Iron Lung vanished from several box office tracking platforms. This led to an emotional livestream from Markiplier where he broke down in tears, thanking fans for their support and acknowledging the “funkiness” of the weekend.
While the “industry vs. indie” narrative gained traction on X (formerly Twitter), experts suggest it was likely a reporting lag caused by the film being self-distributed. Unlike major studios that have streamlined data pipelines to the charts, self-distributed indies often face glitches in real-time reporting. As of today, the film has been restored to its rightful #2 spot.

- He avoided franchise IPs and studio backing
- The film stands on its own merits
Skeptics counter:
- His existing fanbase inflated turnout
- Filmmaking experience matters more than passion
Regardless, Iron Lung has reignited debate about who gets to make movies—and why.
