This episode is another average episode that is just an updated version of a previous story. Here, we see what things have changed since the crew left "shore leave". And, for story purposes, things have changed for the worse. The robots that make the illusions have taken over the planet after the keeper died of old age. Once again, a few highlights, but overall things that aren't that interesting. The main story is fairly good involving the machine that kidnapped Uhura. This may appeal more to the fans of the episode this is based on, but if you didn't care for the TOS story, then it will be the same here. Good, but not great.
This is, of course, a sequel to the original series episode "Shore Leave", and it's one of the few animated episodes that features both an A and a B story; one on a planet and one on the ship. The cutting back and forth between the ship problems and the planet drama is reminiscent of the original series as well as a precursor to Star Trek: The Next Generation. In addition, the episode touches on living machines and features, for the first time in Star Trek, the Enterprise losing gravity. (Both these ideas would be expanded upon in the feature films.) It all adds up to a fun, memorable episode.
