Cinematography:
Special effects/design: Where things look like crap, it's really the fault of the writing. I mean, flying amoebas look like crap - no way around it.
Acting: Shatner's bad, but Nimoy's pretty good for a change.
Music:
Subjective Rating: 7/10 (Good, ). A frustrating mix of good, exciting bits and campy, bad-science bits.
