In this Star Trek, transporters are a new technology, the Federation does not yet exist, and the starship Enterprise is the first Earth Starfleet warp 5 ship. Enterprise is the first human vessel to explore deep space. It is captained by Jonathan Archer, the son of a scientist who pushed for the creation of faster warp vessels and the exploration of space by humans. A lot of the episodes elaborate on the relationships of humanity to other species such as the Vulcans, Andorians, Klingons, and others in the galaxy. There is a lot of emphasis on how different cultures interact, and whether it is a good idea to form alliances with other planets and share technology and interact. A lot of people blame the Vulcans from holding humans back from developing new technologies, claiming they believe we are not ready for such technologies. The origins of the future doctrine known as the Prime Directive has its seeds explained in the course of many"Enterprise" episodes. In later episodes the wisdom of interaction between species is explored more in depth, I think possibly as a metaphor for the existence of racism today, which in "Enterprise" has been eliminated on Earth.
In Enterprise, there is more continuity throughout the series than in earlier Star Trek spinoffs. Especially in the second and third seasons, there is a long arching plot-line throughout, as Enterprise and her crew seek to prevent the destruction of Earth by an alien coalition which is being manipulated by time traveling transdimensional species, who see human beings and the future creation of the Federation as a a threat to their existence. Many of the episodes focus on Captain Archer and the crews attempts to seek out the species determined to destroy them and stop the elimination of humanity. It is a race to find the alien species and stop their weapon, which will be capable of destroying earth and eradicating human beings from existence. Many of the episodes are based on time travel, and I found them interesting.
In most of "Star Trek", the most interesting aspects of the stories are the characters. Each Star Trek series had their own unique characters. Enterprise has some interesting and likeable characters as well, who excel in their fields of vocation and in their possession and practice of heroic virtue. There are also some villains and other characters who are interesting as well. One of my favorite characters was actually the Andorian, Commander Shran, played by Star Trek regular Jeffrey Combs, who can be somewhat of a bastard, but possesses a sense of morality and honor which leads him to practice heroic acts in helping the Enterprise crew and humanity. At first it took me a while to get used to the new characters, but eventually the viewer gets to know and like them very well. The two alien characters on the ship, Vulcan first officer T'Pol, and Denobulan doctor Phlox, are very interesting and likeable. One thing I disagree with is that Vulcans suppress their emotions. To me, Vulcans are almost always pissed off and annoyed at everyone. That is my own observation, and I think it amusing to notice how pissed off the Vulcan characters constantly seem to be. Maybe I am wrong. Decide for yourself.
Overall, I think I liked this spin off of Star Trek more than the others. I recommend checking it out if you have the time, and I hope you enjoy it as well.
