I.S.S.

There is an appealing directness to I.S.S.. It knows it is a thriller, understands the expectations attached to that label, and then looks for small ways to give the material its own voice. Directed by Gabriela Cowperthwaite, it leans on Ariana DeBose and Chris Messina to give the material a human centre. At story level, Tensions, International Space Station and Earth. Reeling shape the central setup, but the later turns are best left for the film to reveal.

⁠

The thriller elements work through controlled information. The film gives the audience enough to stay involved while holding back just enough to create doubt, and the performances make that uncertainty feel like character tension rather than a storytelling trick. Unfortunately, the film rarely settles into a convincing rhythm. Scenes arrive with clear intentions but limited emotional build, leaving the cast to supply weight that the writing has not earned. The premise still has appeal, yet too much of that potential remains on the page.

⁠

Performance wise, Ariana DeBose provides the most dependable anchor, bringing focus to the film whenever the plot threatens to become mechanical. Chris Messina offers a useful contrast in energy, and John Gallagher Jr. helps widen the emotional range of the ensemble. The acting is not equally subtle in every scene, but the group understands the required tone and rarely appears to be performing in different films.

⁠

Thematically, I.S.S. is interested in trust, control and the anxiety created when reliable information becomes difficult to separate from manipulation. That uncertainty gives the suspense a psychological edge, especially when the characters must act before they possess the complete picture. The film is most persuasive when these ideas emerge from behaviour rather than speeches. That additional layer gives the story more purpose than a sequence of familiar genre beats, even if every implication is not explored with equal depth.

⁠

The filmmaking supports suspense through limitation. Framing withholds useful information, the edit stretches moments without stopping them, and sound often points toward a threat before the image confirms it. These choices are familiar, yet they are applied with enough discipline to keep the viewer alert to space, silence and the possibility of a sudden change.

⁠

The largest issue is a lack of dramatic accumulation. Events happen, but they do not build on one another with enough force, and the emotional cues feel imposed rather than discovered. By the final stretch, the film is asking for a response it has not prepared.

⁠

Overall, I.S.S. is more missed opportunity than satisfying experience. There are isolated strengths, but I cannot recommend it beyond very curious thriller fans who prefer steady escalation and psychological pressure to empty surprise.
