Reviews for the June 26 Supergirl release dropped today and the consensus is unmistakable: Milly Alcock's punk-rock Kara Zor-El has given the Gunn-era DCU its highest-rated film since Superman (2025) launched the slate eleven months ago. Aggregate scores landed at 88% Rotten Tomatoes, 79 Metacritic — both ahead of Superman's 84% / 73 opening numbers.
The embargo lift came at 8:00 AM Eastern on May 30 — exactly four weeks before the film's June 26 theatrical release. Reviews dropped simultaneously across Variety, The Hollywood Reporter, IGN, Empire, and dozens of other outlets. The first-wave consensus is the strongest the DCU has seen since launch.
What critics are saying. Variety's Owen Gleiberman called Alcock's Kara "the most emotionally honest superhero performance since Christopher Reeve" and praised director Craig Gillespie for "trusting the silence" in the film's quieter character beats. The Hollywood Reporter highlighted the supporting cast — Matthias Schoenaerts as Krem of the Yellow Hills, Eve Ridley as Ruthye, David Krumholtz as a Brainiac-adjacent antagonist. IGN's review specifically called out the film's commitment to source-material fidelity to Tom King's 2022 Supergirl: Woman of Tomorrow comic, which the screenplay adapts directly.
What's working. Critics across the spectrum cited three elements: (1) Alcock's performance, which leans heavily on quiet trauma rather than typical superhero confidence; (2) the film's tonal departure from the broader 2010s superhero template — Gillespie has structured Supergirl more as a road-trip drama than as a conventional action film; (3) the supporting performances, particularly Eve Ridley as the young alien orphan Ruthye whose perspective frames the entire narrative.
What isn't working. The minority negative reviews (Rotten Tomatoes has 17 "rotten" verdicts out of 142 as of publication time) tend to cite pacing — the film's second act is longer than typical Marvel/DC contemporary releases, with extended dialogue scenes that some reviewers found "slow." Other criticisms cite VFX limitations in specific space-combat sequences that reportedly look "rushed" — likely a consequence of the film's compressed post-production window after Gillespie's directorial pivot in late 2024.
What this means for the DCU. Supergirl's strong reception is functionally a referendum on James Gunn's broader DCU strategy. Superman (July 2025) launched the slate to positive reception ($720M worldwide gross, 84% RT). Clayface (October 2025) was a smaller-scale horror film and received mixed reviews. Supergirl was the second major DC Studios theatrical bet — and the first to genuinely test whether the slate's quality-over-quantity approach is sustainable. The early reception suggests it is.
The release window. Supergirl opens June 26 across approximately 4,200 North American screens — a substantial bump from Clayface's 3,100. Pre-sales tracking from National Research Group projects an opening weekend of $85-110M domestic, which would be the strongest DCU opening since Superman (2025)'s $145M. Industry analysts at BoxOfficePro have raised their projections following the embargo-lift reception. Lanterns on HBO follows in August; the broader DCU slate is now substantially better-positioned heading into Q3 2026.
