I really liked the first part of this episode up to the point that the first technician died and Data had to avoid being killed himself. The Terra-forming team seemed likable and could have been expanded upon. But after Data and Geordi discovered the lifeform, the crew that terrorized it was put mostly into the background, except a scene where Riker consoles one of them which was well done.
The life form's speech was simple but effective, however the rest of the episode past the point of its discovery flatlined and failed to deliver on several opportunities for character development. The fact that inorganic life was unknown was rather strange as Kirk's Enterprise had already encountered several beings like that. Even Q while he takes the form of living beings can be considered inorganic because his race is nothing but energy. All of these established facts and ideals were thrown out the window, and Picard needs to right another wrong accidentally caused by humans.
I give it a mediocre on a decent delivery, but a nosedive at the halfway point that was salvageable.
