Community reviews for Star Trek, shown here with its season details.
The original series may be a bit hard to watch with a modern mind set, but the episodes still contain the key discussions on what it is to be human. Really the show was a great platform for modern thinking and is worth watching to understand the process that people went through to get to the modern day. Yes it is Science Fiction, but really it is Social Commentary.
Before Star Wars, this was a fan favorite for sci fi fans alike! It was campy, cheesy, entertaining, and a little bit pervy! I mean, C'mon, there were scandidly clad women in the show, even for the 60s! And don't get me started on the Starfleet women's short skirts! Probably my best highlight of the show! 😅 But yeah, the original series was the best.
Star Trek (AKA Star Trek The Original Series, AKA STTOS) is a series that has had a dramatic influence across much of the science fiction genre, and as some have suggested, influenced culture around the world. The writing, directing, and cinematography of Star Trek are top-notch, even by today's standards. On par with more recent series like Battlestar 2004. From the top writers and directors of science fiction of that era, sophisticated storylines across the series deal with challenging topics that are risqué even today. Star Trek was radically ahead of its time in the 60’s having a multi-racial main cast including things like non-white character’s and women holding officer positions in Starfleet (unheard of at that time and for decades after) Warning: Some female characters wear mini-skirts (a fade in the 60’s). Some creatures had campy costumes (state of the art in the 60’s). I would recommend checking out “The Original Series Remastered Project” which has the series remastered at 1080p with updated CGI graphics.
