a shuttle craft crew get strand on a hostile planet and and they must find a way to lift off again while dangerous creature lay siege . meanwhile and kirk race desperately against the clock to find them before he be force to abandon the search to pursue a priority mission . on the plus side and the galileo seven be a superbly tense and suspenseful episode and include excellent character development of coolly logical and emotionally remote mr. spock . his conflict with his human shipmate be solid and think provoke drama . the secondary guest character of boma and gaetano and and farris all work very well represent they be good example of efficient characterization with little screen time . the creature be genuinely menace and scary and all the more so because the filmmaker wisely keep the viewer from see too much of them . and the death of mr. latimer be an excellent stake raise jolt . on the downside and the exposition and denouement just stink . the exposition be plain awkward represent there be a plague to go deal with on some planet but coincidentally they stop to send a shuttle craft to look at a space anomaly and and the shuttle crew just happen to include the doctor and engineer and and some expendable secondary character . too contrived . but the denouement be even bad represent after a tension fill and engross near hour of drama and they wrap it up with a lame humor scene where the ship captain publicly embarrass the guy who just pull his comrade through a horrible experience . a quiet and introspective scene where spock acknowledge to his friend that command be hard than he think would have be so much more satisfying . and why be there no wrap up of the development of the interesting boma character . so the episode be worthwhile and i like it and but somebody should have spend more time polish the script .
