The 100 first premiered on the CW Network in 2014. Based on Kass Morgan's novels, one-hundred juvenile delinquents were sent to the ground to die. The series made several and noticeable changes from the books. Following the journey of Clarke Griffin and Bellamy Blake, the series central characters are responsible for leading the hundred, and later, Skaikru. Although at first, the series had a similarity to "Lord Of The Flies," the show changed course, becoming known and remembered for far more. One of it's biggest achievements came in world-building, especially in Grounder culture. The clothing, language, fighting styles, and society itself are all well-developed.
Viewers took to the invented world and found themselves immersed in the characters and their lives. However, not every season was a fan-favorite. This is every season ranked, according to the Rotten Tomatoes Audience Score.
Entire Show: (73%)
Overall, what fans most enjoyed about the series was the interactions between the delinquents and the essence of a found family. Not many of the central characters were actually related, but how they formed their own relationships and families was a beloved aspect of the series.
Some of the reasons audiences were invested for so long came from the show's sci-fi parts and the developing character arcs. Relationships are a key factor in any series, but fans tended to believe that when the main characters were all together, that is when the show is at it's best. Unfortunately, some moments did not match up with what the fans wanted to see in the show.
Season 7: (55%)
The final season of The 100 was not the viewer's favorite. As the last installment spent its time between time jumps, flashbacks, planet jumping, and the stagnant plot on Sanctum, fans found constantly having to go back in time to be irritating. It did not help that lead characters, Clarke Griffin and Bellamy Blake, seemed to take a backseat to the goings-on for many episodes. While the last episodes did an excellent job finishing Octavia and Murphy's character arcs, others appeared not to have as pleasant a finale.
Yet, it was Bellamy Blake's storyline that made the last season the most hated. The final episodes managed to contradict seven seasons of development by having such a beloved character killed by his best friend. Bellamy was not only killed at Clarke's hand, but he died alone without any farewell. To top it off, it is never explained what happened to his body afterward.
Season 3: (58%)
Even with the number of things that occurred during season three, it is mostly remembered for Lexa and Lincoln's deaths. Both Grounders were fan-favorites and loved by the viewers. When it came time for their characters to die, they weren't deaths that audiences approved of. Lincoln died, executed by Charles Pike, for trying to save his people. It was a brutal death for a character that did not deserve it.
Meanwhile, Lexa, the Commander, and warrior, did not die in a respectful way to her character. She did not die in sacrifice or a warrior's death; instead, she was killed by a stray bullet by one of her own people. A bullet that was meant to kill Clarke ended Lexa's life instead. The decision, years after occurring, still angers fans.
Season 1: (76%)
Even after the series finale, season one is still a fan favorite. The first installment introduced the delinquent group dynamics, showing the underdog one-hundred finding ways to survive independently without the council's help on the Ark.
As the delinquents tried to make a home for themselves around their Dropship, they also faced an upcoming war against the Grounders that no one knew had survived the first bombs. Meanwhile, the Ark's oxygen decreases, leading to the eventual decision to land the Ark on the ground.
Season 6: (77%)
Monty's last gift to his friends was a new habitable environment. Unfortunately, it was more of a nightmare than a peaceful atmosphere. Filled with red sun toxin, body-snatchers, and false Gods, Sanctum is not the haven Clarke and Bellamy hoped it would be. With Raven, Murphy, and more still angry with Clarke and things between Bellamy and Octavia still tense, there is plenty of problems in the air.
But, nothing snaps everyone back together like one of their own being killed and body-snatched. When Clarke is the unlucky Nightblood selected to be the new host for Josephine, it is up to Bellamy to find a way to save Clarke.
Season 5%: (78%)
Six years after Praimfaya, things have drastically changed. There is only one habitable environment on Earth, and everyone wants it. The first two episodes focus on how Clarke and Octavia handled the early days after the death wave. Afterward, the storyline follows Octavia and Diyoza as the leaders of opposing groups of people who want the valley. Events such as the Dark Year and the fighting pits have darkened Octavia, giving her a desperate determination to deliver Wonkru to the valley.
The season also interestingly parallels season one, having Clarke and her people be the Grounders when the Eligius Prisoners land. In the end, though, the fifth season ends on a hopeful note when Bellamy and Clarke discover that Monty and Harper used their years in space alone to have their son, Jordan, and find a new habitable environment.
Season 4: (80%)
Picking up where the previous season left off, Clarke and Bellamy are stuck with the knowledge that Praimfaya is coming. A death wave that will destroy everything, covering the world in radiation is difficult to beat, but it is possible.
Everyone is searching for options to live through the radiation or find a bunker to wait it out. The fourth season also shows that not everyone wishes to survive Praimfaya. Overall, season four places plenty of emphasis on the significance of keeping the human race alive and the urgency that comes with the end of the world.
Season 2: (86%)
Season two is perhaps the most significant installment of the series. It expands the world and plot from the first season, upping the stakes and transforming what it means to survive. Although Clarke begins the season trapped in Mount Weather, she quickly escapes, allowing her to take up an integral leadership role with Skaikru and Lexa.
Meanwhile, Bellamy becomes an inside man to help find a way to save the forty-seven. The season places a significant amount of focus on the remaining hundred, showing them fighting for their lives or working to save each other.
