This gripping and thought-provoking film explores the darker aspects of the human psyche and the power of unity in the face of adversity. The film expertly captures the fear of being trapped in an enclosed space, as the passengers desperately fight back against a deadly creature. The storyline compile with multiple themes that includes desperation to live, betrayals, love and the consequences of meddling with nature but some scenes are quite unnatural such as the death scenes and the uncertain fate of the characters makes audiences question the possibility of escape in those situations. Not much of a horror.
