Tv Season Info

With Barry/The Flash (Grant Gustin) voluntarily committing himself to imprisonment in the Speed Force, Iris (Candice Patton) forcefully leads a discouraged Team Flash in protecting Central City. However, a new villain emerges and threatens to destroy the city if the Flash doesn't come out to fight him. Against Iris' wishes, the team brings Barry out of imprisonment, though Barry seems incapacitated by his stay in the Speed Force. Later, the team realizes that by getting Barry out of prison, they played right into the hands of their new enemy, the Thinker (Neil Sandilands). Season 4 of "The Flash" also stars Carlos Valdes as Cisco Ramon, Danielle Panabaker as Caitlin Snow, Jesse L. Martin as Joe West, Keiynan Lonsdale as Wally West, and Tom Cavanagh as Harrison Wells. Danielle Nicolet, Jessica Camacho, Hartley Sawyer, and Katee Sackhoff make recurring appearances as Cecile Horton, Gypsy, Ralph Dibny, and Amunet Black respectively.

Perhaps I'm the only one who feels this way, but the decision to dispense with the meat of the story to skip to the end seems pretty familiar, no?

The Flash Season 4 episode 16, 'Run Iris, Run,' is one of the most exciting moments in series history.

Mar 26, 2018 | Full Review…

As we all know, most Flash episodes are built on three things: heart, humor, and spectacle. Thankfully, this hour wasn't lacking in any of those.

Oct 14, 2017 | Rating: B | Full Review…

The overall storyline plays out well over the 23 episodes, and most of the characters get something to do. A good return to form for The Flash.

Feb 17, 2019 | Rating: 4/5 | Full Review…

A solid season but it's disappointing to see some of the supporting players sidelined here.

Nov 18, 2018 | Rating: 3.0/4 | Full Review…

Enriched with its compelling characters and intricate storytelling, the show remains a shining example of how superheroes on the small screen can easily compete with, and in many cases surpass, their big screen counterparts in terms of quality.

Aug 29, 2018 | Rating: 4/5 | Full Review…

There's a lot that doesn't make sense. Like, a whole lot.

Jun 18, 2018 | Rating: 2.5/5 | Full Review…

The episode sets up the rest of the season, and reminds us just what we loved about The Flash before season three went sideways.

Oct 30, 2017 | Full Review…

There's every reason to hope The Flash has returned from hiatus creatively recharged and ready to deliver on the promise of a lighter, more fun-filled season.

Oct 24, 2017 | Full Review…

It's hard to dislike Grant Gustin, who has such a natural charisma, but the show surely tried. Now, it's letting him have fun again with inventive speedster sequences, new ways of battling foes, as well as familiar interactions among the team.

Barry Is Back, and Better Than Ever...?

Oct 14, 2017 | Full Review…

Every year when The Flash returns I say something along the lines of how good it is to have this cast back. I do genuinely miss this show during the offseason, even if it sometimes gets a little exhausting or frustrating during the post-midseason lull.

Audience Reviews for The Flash: Season 4

  • Jun 12, 2020
    Flash: Season 4 Witness the beginning when the flash series couldn't keep their main plot as entertaining as their filler throughout the season.
  • May 20, 2020
    Barry allen makes stupid decisions that kills innocent people, yet he continues to preach don't kill anyone. He is selfish garbage.
  • May 14, 2020
    wow just wow this was great
  • Apr 21, 2020
    An improvement on season 3, but still lacks the charisma of the first 2 seasons. The Thinker was a better villain than Savitar and a nice change from Barry confronting another speedster, but the downfall for him was very anti-climatic. The season was mediocre the whole way, never really peaking my interest. Harrison was the standout character this season, as he received more of an arc, and was not a new Wells who would ultimately be killed off by the end. The rest of the cast is fine, but Grant Gustin as Barry is still the standout. There is a lot of set up for season 5, so hopefully the show picks up again.

    Season four of the flash abandoned its darker settings of the previous two seasons and debuted with a brand new suit for the fastest man alive. However, it struggled to find plots and characters that matter. Although starting strong it couldn't finish the same way.
  • Feb 23, 2020
    Weakest season of the series so far. The Barry goes to prison plot line is the most ridiculous "twist" ever and that's saying something in a comic book series where people travel the multiverse and sentient gorillas wreak havoc.
  • Jan 14, 2020
    Featuring a menacing villain magnificently played by Neil Sandilands, beautiful visual effects, great action scenes, a neat script, nice direction and charismatic performances by Grant Gustin, Candice Patton, Danielle Panabaker, Carlos Valdes, Keiynan Lonsdale, Tom Cavanagh, Jesse L. Martin, Danielle Nicolet and Hartley Sawyer, The Flash's fourth season continues the show's high-quality
  • Jan 06, 2020
    honestly i just didn't like the villain
  • Dec 29, 2019
    Good start with an interesting and subdued villain that had a lot of potential. By the it fizzles out and turns the villain into an over the top cartoony nonsense
  • Dec 18, 2019
    Season 4 gets a little more silly but Thinker is a amazing villian and just another solid season.
