||Well, it was dramatic and sort-of tense, but a fairly basic story. One highlight was Leonard Nimoy, who spent much of the episode twitching and sometimes writhing, trying to show Spock's inner struggle against the creature possessing him. There was also his calm reaction to being blinded, and the way he allowed his eyes to wander, all very good non-verbal acting. The creatures themselves were not exactly convincing, but the concept was probably better thought-out than Voyager's "Macrocosm". The new visuals were excellent, as ever. We had a really nice shot of the Enterprise deploying a satellite through a small hatch in the engineering section. A very good idea to explain what these hatches are. Overall, not too bad, but nothing special.
