Star Trek: The Original Series Season 1 is available to watch in the watch it now feature on Netflix. I've never seen any of these episodes. I just watched the first episode named The Man Trap. It is just OK, but I'm very surprised at the special effects. They are much better than I expected them to be.
I will update these as I watch, but Season 1 is 29 episodes, it may take a while. Instead, I will just post updates on the really good ones.
