Isabelle Sieb

In Hostage (2025), there is little waiting between emergencies. Sieb and fellow director Amy Neil keep the five episodes moving, helped by editors Ben Drury and Jesse Parker. We were grateful for the pace, which kept us watching when the connections between events grew unconvincing. The short run suits a series with enough tension to entertain thriller devotees and too little care for the logic of its crises. It gives us a reason to watch Sieb's work, without making every brisk passage evidence of a personal signature.

Her earlier credits suggest how much of that work involves adapting to different kinds of pressure. After directing the opening block of The Athena (2019), she took on three episodes of the submarine thriller Vigil (2021), two of The Devil's Hour (2022) and three of Nautilus (2024). Confined suspense and demanding underwater action call for practical judgement about what an audience needs to see and when. By Hostage, on which she directed three episodes including the first, she had substantial experience of those demands.

Her approach to actors is based on trust and discussion, with the director helping them understand a character's feelings scene by scene. She is also willing to rethink scenes in the edit rather than defend the first version. That sounds sensible, and Hostage certainly benefits from Suranne Jones and Julie Delpy, who keep it watchable when the writing falters. Their contribution matters to our verdict as much as the efficient handling of the emergencies.

The reservation is that Hostage sometimes moves quickly enough to conceal a weak connection rather than resolve it. Drury and Parker's cutting maintains urgency, but cannot supply the reasoning the series lacks. Sieb's interest in balancing tension with character intimacy is worth following, particularly with material that can withstand a slower look. Try Hostage if brisk suspense is enough for the evening; its political reasoning will not repay closer attention.
