I have fond memories of watching this animated "Star Trek" show when I was a kid via satellite dish on Sky Channel. It prepared me for the live action version and when I rewatch these episodes now it is easy to see why I liked it. The series used the same voice cast as in the original series. It had many of the same writers who delivered some interesting stories and even delivered a good background story on Spock. What was not that great was that the animation was pretty static and repetitive at times and that there was not enough character moments to give the show a true depth. It was sadly also disowned by the creator and a long time was not available to see, but luckily it is now possible to see it again. It is not a masterpiece but it gives fans what they want: additional adventures with their favorite crew and it do feel and look like the original show without overdoing it which is nice.


It's a serie that's nice to see once. But not that special. Some aliens a bit too crazy for me and very stiffly animated.


Great premise, I LOVE that they got the original voice actors all to reprise their roles, and I liked that they could show a more alien-diverse universe than live TV technology could do at the time. And some episodes were pretty decent. HOWEVER, this series got worse and more ridiculous as it went along. Since it was a Saturday morning cartoon, that's to be expected I suppose, but it still got harder to watch by the end. In the end, I just felt like the best thing it did was give us an endless array of hilarious screenshot and animated gif possibilities.
