When nuclear Armageddon destroys civilization on Earth, the only survivors are those on the 12 international space stations in orbit at the time. Three generations later, the 4,000 survivors living on a space ark of linked stations see their resources dwindle and face draconian measures established to ensure humanity's future. Desperately looking for a solution, the ark's leaders send 100 juvenile prisoners back to the planet to test its habitability. Having always lived in space, the exiles find the planet fascinating and terrifying, but with the fate of the human race in their hands, they must forge a path into the unknown.

"Damocles - Part Two" is one of the best episodes of the season, and the final 10 minutes shift the narrative in really exciting ways.

When showrunner Jason Rothenberg said that the fifth season finale of The 100 could have made a "satisfying series finale," he wasn't kidding.

The 100 has always loved to try and shock its audience and what could be more shocking at this point then our abused and cynical characters to reach to hope?

The 100 is best when it is driven not by the plot, but by the characters we love so dearly.

Season 5 of The 100 is a very dark season, and so many relationships were tested in this season. Everyone soon reunites after Praimfaya, and everything goes down from here. Watching Octavia be ruthless to everyone she once cared about was sad to see, and the way she ran things was corrupt. Bellamy (Bob Morley) and his crew came down from space, only to find that Clarke (Eliza Taylor) was still alive but captured by a new enemy. There was only one survivable place on Earth, and this group of prisoners was trying to take it over. People from Octavia's crew were also working with the enemy, because they didn't want Octavia to ruin the last piece of land. Madi (Lola Flanery) was a big part of this season, and she was the one who brought everyone together to defeat this enemy. What happened at the very end of this season was detrimental, and it forced the entire group to go back up into space and into cryosleep. Overall, Season 5 was pretty decent, but the show only goes down from here.

Season 5 really changed the tone of the show, especially with how intense the character dynamics became. It felt darker but also more layered. I came across a fan discussion on Grounders Source that explored this shift, and it made me appreciate this season even more.

An incredibly strong, dark season. The time jump reinvents the show in a way, and changes a lot of dynamics quite a bit. Although I do not agree with some of the writing (Bellamy and Echo, Clarke being treated as a villain and not being appreciated by Spacekru), it is still such a strong season from start to finish. The main enemy (the prisoners) were interesting enough, but truthfully, the primary focus of the season for me was Octavia/Blodreina. One of the coolest storylines in the whole series. The finale is also one of the strongest episodes of the show. Also truly LOVED the Clarke and Madi dynamic. This season was highly anticipated and certainly delivered in most areas, even if the writing was a bit subpar.

The harsh turn in sides of the characters in this season is truly enjoyable. Then mix in the entirely new concept that they reveal. It truly is amazing. My top comfort show.

I'm almost done with this series, I didn't want time to pass so quickly.
