James Gunn’s Potential Justice League Movie: A Cautious Hope Amid High Stakes

James Gunn’s Superman has hit theaters, kicking off the rebooted DC Universe (DCU) under his and Peter Safran’s leadership at DC Studios. Our review of Superman struck a cautiously optimistic tone, praising its vibrant energy, David Corenswet’s stalwart Clark Kent, and a return to the character’s hopeful roots. However, we didn’t shy away from its shortcomings: an overstuffed narrative, uneven pacing, and a sprawling cast that sometimes dilutes the focus. Even its strengths—one or two sharp performances and comic-book flair—came with caveats, as the film’s ambition occasionally outstripped its execution. With reports of a potential Justice League movie on the horizon, we’re intrigued but wary. Gunn’s track record suggests he could pull off a team-up film, but the DCU’s success hinges on avoiding the pitfalls that plagued both Superman and the DC Extended Universe (DCEU).

A Deliberate Path to Justice League

Per a Wall Street Journal report cited by ScreenRant and IGN, Gunn and Safran are planning a Justice League reboot, but they’re taking their time. Unlike the DCEU’s 2017 Justice League, which rushed to unite its heroes and flopped with a $661.3 million global gross against a $300 million budget, the DCU claims to be prioritizing individual character introductions. Though this film’s somewhat forced inclusion of the Justice Gang seems to contradict this.

                   

Superman, with its $225 million budget and projected $115–130 million domestic opening weekend, is the foundation. Early box office numbers suggest it could hit $500 million globally, a promising (if modest by early MCU standards) start for a franchise aiming to rebuild trust after the DCEU’s collapse. The plan is to establish heroes like Batman, Wonder Woman, and others through solo projects before assembling them, a strategy that could pay off if executed with a little more precision.

Our Superman review praised David Corenswet’s warm portrayal of Clark Kent, which brought a kind-hearted depth to the character, but we criticized Rachel Brosnahan’s Lois Lane for feeling unpleasant and lacking any chemistry with the iconic hero. We also noted the film’s struggle to balance spectacle with heart, often leaning too heavily on action and spectacle at the expense of emotional clarity and a natural causal narrative structure. The film’s tendency to cram in characters—like Nathan Fillion’s Guy Gardner, Edi Gathegi’s Mister Terrific, and Isabela Merced’s Hawkgirl (just the worst)—created a “Justice Gang” that felt cluttered rather than cohesive. The DCEU’s team-up failed partly because it prioritized (a convoluted) plot over character; Gunn’s knack for ensemble dynamics (Guardians of the Galaxy, The Suicide Squad) gives us hope, but we’re skeptical about scaling that to DC’s most iconic roster and tonal parity.

Spinoffs and World-Building: Opportunity or Overreach?

The Wall Street Journal reports potential Superman spinoff shows for Mister Terrific and Jimmy Olsen. Edi Gathegi’s Mister Terrific, with his tech-genius persona, could anchor a compelling series, fleshing out a hero who fits the DCU’s vibrant world. However, we found Gisondo’s Jimmy Olsen to be a practical non-entity—neither distracting nor impactful enough to justify a spinoff, despite the everyman perspective he could offer. These projects align with Gunn’s plan for two live-action films, one animated film, and several HBO Max series annually, building an interconnected DCU.

But here’s where our caution deepens. Superman’s narrative bloat—trying to set up a 300-year metahuman history while introducing a dozen characters—often undermined its strengths. Spinoffs risk further stretching the DCU’s focus, especially if they prioritize world-building over standalone storytelling. The DCEU’s overambitious crossovers left audiences fatigued, and while Gunn’s character-driven approach has potential, we’re concerned about diluting the DCU’s momentum with too many threads. Superman’s 95% Audience Score on Rotten Tomatoes and strong presales ($20 million and counting) suggest fans are on board, but spinoffs will need to earn their place rather than coast on this film’s goodwill.

The DCU’s High Stakes

Gunn’s broader DCU slate—The Brave and the Bold (Batman and Damian Wayne), Supergirl: Woman of Tomorrow, Creature Commandos, and Peacemaker Season 2—shows a commitment to a unified vision across mediums. His decision to cancel a greenlit DCU project over an unready script signals a focus on quality, addressing our review’s concern about Superman’s rushed pacing and overcrowded plot. Still, the DCU’s success rests heavily on Superman’s shoulders. The DCEU’s failures (Batman v Superman’s grim tone, Black Adam’s $393 million flop) loom large, and Warner Bros.’ past attempts to court Marvel’s Kevin Feige or even Dwayne Johnson highlight the studio’s desperation for stability.

Our Superman review appreciated its attempt at an optimistic tone as a corrective to the DCEU’s gloom. Still, we noted its struggle to balance action, character, and setup, often feeling overstretched. A Justice League film would face even greater scrutiny, needing to unify DC’s biggest heroes—whose mythic, grandiose stature sets them apart from Marvel’s more grounded roster—while delivering the emotional clarity we found uneven in Superman. Gunn’s irreverent, character-driven style, honed in Marvel’s Guardians of the Galaxy and The Suicide Squad, gives us cautious confidence in his ability to craft compelling teams, but we’re concerned his playful tone may clash with the towering gravitas of DC’s pantheon. The scale of a Justice League project could also expose the same cracks we saw in Superman—overambition and narrative sprawl—if not tightly controlled.

A Hopeful but Watchful Eye

A Justice League movie under Gunn’s direction holds immense potential, but it’s far from a sure thing. Our Superman review found that the film, while earnest in its attempt to revive the character’s hopeful spirit, lacks a distinctive visual style and struggles to deliver the emotional depth we’d hoped for, often feeling muddled under its ambitious scope. We’re intrigued by the prospect of a Justice League that captures the team’s iconic camaraderie while avoiding the DCEU’s mistakes, but our reservations about Superman serve as warning signs. Gunn must streamline his vision, ensuring each hero shines without being overshadowed by excessive setup or spectacle.

As Superman continues its theatrical run, its performance will shape the DCU’s path. If Gunn can build on its strengths and address its flaws, a Justice League film could redefine DC’s cinematic legacy. For now, we’re hopeful but vigilant, eager to see if Gunn can unite the World’s Finest without losing the human touch that made Superman a faltering step in the right direction.
