The 100 refers to a TV series which airs on the CW network. It is set some 100 years after a major nuclear war on Earth.
Don't read this article if you intend to watch the show. Certain plot details may be revealed here.
Science Fiction Premise
The series starts by describing the current state of humanity about 100 years after major nuclear radiation occurs on Earth. At that time, a group of people survive only because they are orbiting the Earth in space stations. Civilization continues in the relative safety of space.
A group of people is cast out from the space station. They are sent to Earth where their prospects are quite bleak. The radiation may kill them. Unseen dangers await. Since the alternative is death for those who remain in orbit, they willingly accept the danger of a return to the planet.
Many of the main stars are young people. This presents an interesting dynamic. They are filled with the passion and energy of youth. As a result, the audience roots for the group. There are many interesting relationships between the cast. Some of these have sexual tension while for others, the stress of a boss/master arrangement is shown. The typical divisions of cast into heroes, villains, and undecideds, comes through. This leaves a lot of room in the show for big changes during the episodes.
Strong Women Characters
This show is quite unusual because it has women in very important roles. In each of the relationships, the woman is quite equal to the men she deals with, or even superior. This is true regardless of the age of the character in the show. Women in the cast are doctors, leaders, scientists, engineers, soldiers, and more. Perhaps it is the strength of the women characters that makes this show as entertaining as it is.
On the flip side, some of the male characters are fairly shallow. This is mainly evident with the younger characters, not so much with the older leaders. Inconsistent plots leave the viewers unable to determine exactly what a given man is going to do on the show. This is really true of some of the space people, less so for those that have lived on the ground.
The various episodes show a clear advanced technology in many ways. They show that that the human race was able to live in space, in great numbers. There are many pieces of advanced equipment at their disposal. Unfortunately, they people are in a constant struggle for survival. The extremes between advanced technology and possible death are a little hard to take. One would think that an advanced technology would be able to establish a more reasonable balance, especially since they have well over 1,000 people on a space station at one time. The viewer is left to accept that technology is not an absolute. Progress is not constant. With this realization in mind, much of the plot can be more easily accepted by the viewer.
As the episodes progress, there are several instances where conspiracies are borne. The advanced society is extremely harsh. People slowly rise up against it. The same happens for those sent to Earth. Rebellion is a constant threat. The leaders always resort to extremely brutal, but effective, responses to any possible questions of leadership. They certainly have the power to defend their establishment.
The 100 does show that in many ways, a modern society can revert to a more primitive order. As the people descend from their established ways, they readily accept the reality of their new life. Food becomes scarce. Threats from warring people exist. All resources are in short supply. When part of the group leaves space and lives on the ground, they easily adapt to a new set of problems. The old problems, while serious, are completely left behind and replaced by the new set of problems. There is no time for remorse by any character. In fact, basic recollections of their prior lives is hardly explored, ever. People just accept that their lives are changed in major ways. They begin to adapt immediately, or they die. This is seemed to be normal by the characters.
The space station clearly has ample gravity. No one floats around in space. There is normal motion by all people and objects. No explanation is given for the presence of gravity. The space station structures are very large but they don't seem to be rotating enough to instill artificial gravity. The great science fiction writer, Arthur C. Clarke, depicted orbiting stations having a substantial amount of rotation which would cause a force of gravity to be generated. This is not shown in this show. As well, the directors do not offer a compensating force. No one wears magnetic boots. There is no magic force in place to replace the spin which would generate gravity. It is simply never mentioned.
Food is another problem. In space, with nearly 2,000 people, a great deal of area would have to be devoted to the production of food. This is never mentioned. There are shortages, but the farming infrastructure is not explored.
On the ground, the food is not described much more. The people do resort to hunting, and they have some success, but not to the degree that would be necessary to sustain as many people as there are in the village.
There are some shots which so various monuments. Unfortunately, the vegetation is completely unlike that which exists where the monuments are currently located. Perhaps the monuments were moved by persons unknown. Perhaps the Earth of the future has a big climate change and vegetation is quite different that it is today. This is never explained. Instead, the viewer has to assume the the monument references are placed in order to generate visual, or emotional, impact. The alternative, a global upheaval, could not reasonably occur within the time span of the civilization described.
Despite the minor problems mentioned, the series is quite entertaining. The plot is exciting. The characters are interesting. The predicaments are engaging. This makes the show quite worth checking. Look for it on the CW network, or on Netflix in Canada.
