Tv Season Info

The fourth season of The CW's post-apocalyptic science fiction series continues to chronicle the lives of a group of former juvenile delinquents who were sent away from the space colony that was their home in order to repopulate the Earth, which had been uninhabited by humans for a century following a nuclear fallout. Over the years, the fight to survive has led to lives full of betrayal, fear, and loss for Bellamy (Bob Morley), Clarke (Eliza Taylor), and the rest of their group. And a devastating revelation has made their future all the more uncertain.

I can't emphasize enough how much I love this show, and how much I feel like it so perfectly combines the moral quandaries of society with the complexities of human emotion on screen, through a balanced cast of adult and teen characters no less.

"Priamfaya" launches the show into a whole new world and wraps up Season 4 with one of the most exciting, and dare I say hopeful, finales yet.

Obviously, this is a fantastic, full-circle parallel to the 100 teens who landed on earth after an apocalypse back on The 100 Season 1 Episode 1.

Everything old is new again, and I have a feeling Clarke and her nightblood friend are in for some trouble.

Feb 2, 2017 | Rating: 3.5/5 | Full Review…

Season four finally premiered and brought with it some much-needed answers: ALIE was telling the truth.

A fitting end to a season of The 100 that bounced back from the third season's major missteps.

The 100 deals with loss, grief, and trauma in just about every episode, and it's smart and nuanced in its portrayal of how humans confront all three.

Feb 3, 2017 | Rating: 4/5 | Full Review…

For longtime fans of The 100, the new season finds viewers rewarded with a deeper look at the characters, including what drives them and what it takes to have them make unexpected and sometimes questionable decisions.

Feb 3, 2017 | Rating: 4/5 | Full Review…

Octavia has gone through an amazing metamorphosis from an unsure girl who led a very solitary, even lonely, life into a rock-solid, kick-ass woman who can handle any situation laid in her path.

    Murphy (Richard Harmon) was excellent in this season. Every second that he's on screen and everything he says is pure Gold

    "The 100" é uma série habilidosa, capaz de concluir os seus dramas anteriores e de garantir uma nova história para ser continuada. Mesmo que algumas coisas necessitem de ser melhoradas, esta temporada mudou de figura e conseguiu alcançar uma nota positiva, apesar do "haterismo" que a rodeia.

  • Jul 09, 2018
    Leads to a final episode that's gripping and intense, and does a huge justice to what the series has become and where it can go.

    I don't get why fans hate this season. It's better than season 3 and it's actually really ENJOYABLE!
  • May 16, 2018
    I wish this show wasn't sooooo boring. it has a great apocalypse idea. the execution is just soo crappy. you can have a very low iq an understand what's going on but you'll need a even lower one to not pick it apart and wish you didn't waste the time watching it.
