This old Saturday morning chestnut from the 70s isn't considered by some purists to be part of the so-called "Star Trek" canon. I'm not sure why, since the main characters are voiced by the same actors (James Doohan also provides voices for a lot of other characters), and many episodes feature stories creative & intelligent enough to rival the original show. Maybe it's because it's so cheap looking. The animation is downright awful, even for the early 70s, and the cheesy stock music score doesn't help much. But for me, this was a wonderful nostalgia trip, and I enjoyed seeing these old cartoons again. Whether or not I'd want to sit through them again is another story. All 22 episodes, some with optional audio or text commentary, are included in this nicely packaged box. And, since there's nothing else related to "Star Trek" left to release on DVD, completists may want to pick this up. From Paramount
