I have mixed feelings about this lunar horror. While the movie succeeds in creating a claustrophobic atmosphere and delivers some decent tension, it ultimately falls short of its intriguing secret-NASA-mission premise. The first half builds tension admirably, but the latter portion falls into predictable territory. The small cast performed well, though the characters could have been better developed. The reveal of the threat, while interesting conceptually, feels underwhelming in execution. The ending is predictable and lacks the impact it clearly aims for. It's worth a viewing for fans of subtle sci-fi horror, though it may leave others wanting more.
