Two Hours Used to Be the Sweet Spot — So Why Does Every Movie Feel Like the Wrong Length Now?

Somewhere between the three-hour director's cut nobody asked for and the 94-minute streaming version that feels like someone fell asleep in the editing bay, there's a version of this movie that actually works. Finding it has become one of Hollywood's most persistent, least glamorous problems.

Runtime used to be a fairly settled conversation. The two-hour film was the industry standard for decades — long enough to feel substantial, short enough to fit two screenings per evening at a multiplex. Then streaming arrived, attention spans became a topic of constant public debate, and directors started treating their films like novels. Now nobody agrees on anything, and audiences are the ones absorbing the confusion.

The Multiplex Math That Still Runs Everything

Theatrical exhibition has always had a practical relationship with runtime. A film that runs 90 minutes fits comfortably into a three-screenings-per-day schedule. A film that runs 160 minutes eats into that calculus significantly, which translates directly to how many screens a theater is willing to give it and for how long.

This isn't a creative conversation — it's a real estate conversation. Every extra ten minutes of runtime is a negotiation between a studio and an exhibitor over how much of the day that film gets to occupy. Which is why, historically, studio executives have leaned on directors to trim, and directors have resisted, and the final cut of most major releases is the product of that tension more than any pure artistic vision.

The multiplex math hasn't changed. What's changed is that it now has to compete with a completely different set of incentives from streaming platforms — and those incentives point in opposite directions depending on who you ask.

What Streaming Actually Wants (And It's Complicated)

The conventional wisdom says streaming platforms want shorter films because of shorter attention spans. The data is messier than that.

Netflix's internal engagement metrics — which the company has been reluctant to share publicly but which have leaked into industry reporting over the years — suggest that completion rate is a key performance indicator for content. A 90-minute film with a 70% completion rate might actually underperform a 150-minute film with a 55% completion rate in terms of total minutes watched, which is what platforms ultimately care about.

This creates a genuinely weird incentive structure. Platforms aren't uniformly pushing for short films. They're pushing for films that keep people on the platform as long as possible, which sometimes means longer films and sometimes means shorter ones, depending on the genre and the audience.

Where things get genuinely problematic is when films are cut specifically for streaming consumption without the director's involvement. There are well-documented cases of theatrical films being trimmed by 15 to 25 minutes for their platform debuts — not for creative reasons, but to fit algorithmic assumptions about when viewers drop off. That's a different conversation from a studio asking a director to tighten a third act. That's post-production interference with a finished work.

The Case Studies That Should Make You Angry

Zack Snyder's Justice League is the most famous recent example of the runtime debate going fully public. The theatrical cut that Warner Bros. released in 2017 — heavily edited by Joss Whedon after Snyder's departure — ran about two hours. Snyder's original vision, eventually released as the Snyder Cut on HBO Max in 2021, ran four hours and two minutes.

Leaving aside the quality debate, the existence of both versions illustrates something important: the theatrical cut wasn't the film as conceived. It was a film shaped by studio anxiety about runtime, multiplex scheduling, and audience attention spans. And enough people cared about the difference to fund a genuine fan campaign that ultimately cost Warner Bros. somewhere in the range of $70 million to complete and release the original version.

On the other end of the spectrum, Rian Johnson's Knives Out — which runs 130 minutes — was considered a risk for a mid-budget whodunit. It performed exceptionally well both theatrically and in streaming afterlife, suggesting the runtime concerns were overblown. Its sequel, Glass Onion, ran 139 minutes and became one of Netflix's most-watched films of 2022. Neither film felt long. Both films knew exactly what they were doing with their runtime.

The difference isn't length. It's pacing — and pacing is a craft issue, not a math issue.

The Attention Span Argument Is More Complicated Than It Sounds

The cultural conversation about shortened attention spans is real, but it's often applied to film in ways that don't quite hold up under scrutiny.

Yes, TikTok and short-form video have conditioned a lot of viewers — particularly younger ones — toward faster content rhythms. Yes, people watch movies on phones and laptops where distraction is a single notification away. These are genuine variables.

But the films that have broken through in recent years — Oppenheimer at three hours, The Irishman at three and a half, Avengers: Endgame at three hours and one minute — suggest that audiences haven't lost the capacity for long films. They've lost the patience for long films that don't earn their runtime. That's a different problem, and it's a solvable one.

The 90-minute film that drags feels longer than the 150-minute film that doesn't. Anyone who's sat through a poorly paced thriller knows this viscerally. Runtime is a symptom, not a cause.

What the Goldilocks Zone Actually Looks Like

For theatrical releases, the data still generally supports the 100-to-120-minute range as the commercial sweet spot for most genres. Comedies tend to work best under 100 minutes. Thrillers and dramas have more flexibility. Action blockbusters have essentially unlimited latitude as long as they keep moving.

For streaming, the calculus is genuinely different — and more forgiving in some ways. A film on a platform doesn't need to fit a multiplex schedule. It doesn't need to worry about whether someone can make it to a 10pm showing after dinner. It can breathe a little more. The irony is that streaming, which is often blamed for pushing films shorter, actually has the infrastructure to support longer, more ambitious cuts — if platforms chose to prioritize them.

The real problem isn't that Hollywood can't figure out movie length. It's that theatrical and streaming incentives have diverged enough that the same film is now being optimized for two different viewing contexts that want different things. Until those contexts converge — or until studios start making explicit decisions about which context they're actually serving — audiences are going to keep watching movies that feel like they're either missing something or overstaying their welcome.

Somewhere, in a edit bay, there's a version of this that's exactly right. Whether you ever get to see it depends on a lot of things that have nothing to do with the film itself.
