Star Trek: The Original Series - Season 3
Star Trek is one of the biggest franchises ever. I first came across it with The Next Generation series. So, when the blu ray of the original came out, I jumped on it. The blu ray presentation–in terms of quality of image and sound–is unparalleled for any series of its time. I was blown away that a series this old could look and sound this good. Now the actual material was a little more uneven than I expected. Some of it is brilliant (Menagerie, Balance of Terror, Court Martial), some of its good, but there is some that is bad, really bad (The Man Trap, Miri, Shore Leave). I watched in utter disbelief as Sulu pranced around in one episode swinging a sword! Yes, there are number of these horrible moments. Of course, there are moments of brilliance and episodes where you see the future potential of the series. Menagerie Parts 1 & 2 is one of those. Jeffrey Hunter is brilliant and the story is one of the best of all Star Trek. BTW, Kirk and Spock are really, really good episode after episode. There are a number of good guest performances and even some surprising ones (like Joan Collins). Overall, it’s ok, but not the best.
It’s all about the original series - this is Star Trek, everything else - even good stuff like Next Gen or DS9 is basically good fan fiction!
There are episodes among the classic 79 that don’t work but this show is more than the sum of it’s parts and I can’t think of one show from the sixties, with the exception of the Twilight Zone, that is just as brilliant, insightful, and entertaining as Star Trek.
The Blu-Rays are terrific and the price is amazing - it’s taken many years for Paramount to do right by Star Trek fans, and these season sets have been well produced and very affordable - this is a must own for any Star Trek fan or anyone who enjoys classic TV.
