This movie involves a reporter persuading a small news team to venture beneath Sydney into the neglected railway tunnels in order to expose a secret plot. It evokes "The Descent," sharing that claustrophobic underground setting. The cast delivered strong performances, and the tunnel environments were appropriately unsettling, creating an atmosphere of palpable tension that was enjoyable in its intensity. Several startling moments genuinely caught me off guard. Even with these positives, it doesn’t offer much beyond standard expectations for this kind of story, though everything is executed competently. It's a worthwhile watch.
