Critic Reviews for 12 Monkeys Season 4

All Critics (11) | Top Critics (2)

12 Monkeys is a sweet ride with plenty of moments to reward continued attention.

Jul 13, 2018 | Full Review…

12 Monkeys takes the good stuff from the movie...and builds upon it, creating a driving narrative that only occasionally confuses -- in the best way possible -- when skipping back and forth in time.

Feb 4, 2019 | Full Review…

Season 4 is, hands down, the best season of the show and every episode tops the last. There's no way I could have predicted 95% of what's happened this season and yet everything feels organic.

Feb 4, 2019 | Full Review…

"The Beginning" is as perfect an ending as you're ever going to see, as everyone gets a chance to right their wrongs.

Feb 1, 2019 | Full Review…

One of the best series on television has just wrapped one of the best finales of the year. As for time, well -- this four-season run has absolutely been time well spent.

Jan 31, 2019 | Full Review…

12 Monkeys has a surprising amount of thematic depth for a show that sets a climactic battle in its finale to the strains of "Time of My Life" (you know, from Dirty Dancing).

Jul 9, 2018 | Full Review…

It couldn't have been scheduled more beautifully if we had planned it ourselves.

Season 4 gets off and running.

Jun 21, 2018 | Rating: B+ | Full Review…

Whether in its efforts to break the twisty narrative loop it has created for itself or find the beginning of the end by going all the way back to the beginning of the story, 12 Monkeys season 4 manages to deliver enough surprises...

Jun 18, 2018 | Full Review…

Needless to say, the writers can't make a wrong choice here; any direction they choose is bound to be an exciting one.

Jun 18, 2018 | Rating: 5/5 | Full Review…

From the word go, the final season of 12 Monkeys pulls no punches. In fact, it raises the bar on "going there" television.

Audience Reviews for 12 Monkeys: Season 4

  • Oct 11, 2019
    Strong run from pilot to finale. Easily within Top 5 of sci-fi series.
  • Oct 11, 2019
    Yes it didn't disappoint. Wonderful twists
  • Aug 19, 2019
    Almost perfect....great ending, questions answers, kept the complex timeline in check without clouding it for the end, and the characters continued to be interesting.

    Hopefully they're many more seasons

    The complexity to which the stories and characters are woven together over 4 seasons is superb. I was originally skeptical when the series was announced. What could it add to the "12 Monkeys" movie mythology? I am happy to say that I was very wrong. "12 Monkeys" is one of the best sci fi shows E-V-E-R on TV. There's something for everyone. There's time travel, apocalyptic events, a love story, life lessons and great humor. Jennifer Goines (Emily Hampshire) is one of the highlights of the series. The WWII episode where she sings Pink's "U + Ur Hand" to a room full of Nazi officers is a delight. So what have we learned from "12 Monkeys"? No matter what the odds, never given up. Hope always wins over despair. Love transcends all (even time). Live in the moment because that's all we have.
