One of the best tv series in sci-fi category. I watched many tv series in my life, over 10k in total... The tv series industry, can't really boast with a big number of tv series better than Star Trek The Original Series - Season 1. In my opinion, some of the actors roles were just a masterpieces. Star Trek The Original Series - Season 1 is worth watching online, espacially if you can watch it for free here. Whoever has not seen it yet, let it rush in front of the TV, because this tv series just has to be seen. The whole tv series is still very relaxing and motivating. Forget the torrents, watch it online on GoMovies.
