The Guardian review says Netflix thriller “The Whisper Man” turns repetitive for Robert De Niro

A film review published by The Guardian on August 28 argues that the Netflix thriller The Whisper Man fails to land as a compelling crime story, with the paper saying Robert De Niro appears to “sleepwalk” through what it calls a “silly” potboiler. The review frames the movie as an installment of low-impact, mid-level streaming programming rather than a sharp, suspense-driven feature.

The Guardian’s critic places De Niro’s involvement in the context of what the paper describes as a run of diminishing returns, noting that the actor has appeared in other projects in recent years that the paper characterizes as lacking momentum. The review specifically references last year’s Scott Eastwood-led actioner and a separate project titled The Alto Knights as examples of how, in the critic’s view, De Niro’s recent choices have not significantly improved outcomes.

Beyond performance, the review’s main thrust is that the thriller’s construction does not maintain audience interest. The Guardian writes that the production comes across as “cheaply made” and, as it progresses, becomes “increasingly uninteresting.” It suggests that the film does not meaningfully build tension or differentiate itself from familiar serial-killer and father-son pursuit premises.

The plot outline, as presented in the review, centers on a father and son who are required to work together to confront a serial killer. The critic’s assessment is that, despite the core setup, the film does not deliver a satisfying escalation of suspense, instead moving through material that the review describes as disappointing and notably unengaging.

The Guardian also uses its review to compare the movie’s overall tone to earlier moments it characterizes as a “cursed” period for De Niro-led genre work. In doing so, the publication indicates that the film’s shortcomings feel less like a temporary misfire and more like a regression to the kind of streaming-thriller craftsmanship the critic says audiences have learned to distrust.

As with any single critic’s review, the assessment reflects The Guardian’s standards and interpretation, not a universal consensus or a formal rating across outlets. For viewers deciding whether to watch on Netflix, the review’s emphasis is on limited creative impact, along with the paper’s view that the film’s approach to suspense and pacing does not justify the premise.

Netflix, as the distribution platform, and the film’s creative team were not directly quoted in the provided material. The key next step for audiences who want more verifiable production context would be to consult additional reviews and official release materials about the film’s cast, creative credits, and marketing claims for suspense and style.
