OAD: 2/13/1989 OK, let's get the elephant in the room out of the way first. This episode had what I feel is the worst reuse of an existing model or effect in the show's history. I know people complained about Spacedock in the Binar episode, but this was a hundred times worse, IMO. The Regula station was pretty small, and the size of many of it's design elements (or those of the Dockyards station that it started out as) were very pronounced. While it often bugged me how so many planets were "Starbase XYZ", I would have much rather seen a planet used than the reuse of the station from the movies. OK, that's done. Now for the story. I'm torn on this one. If I ignored logic, it was pretty good. Data may have crossed the "emotions" line, but not so much that it detracted from the story. Riker's conflict was good--another interesting use of the most versatile character in Star Trek. But this is a story that shouldn't have been able to happen. Data had been an officer for 20 years (give or take) at this point. He had multiple commendations, and had served on many ships in many different functions. At no point in the past had anyone asked the question "Is this guy sentient or not?"
