Critic Reviews for The Darkness and the Light

Speaking of natural charm, it has been a while since we were treated to a whole episode with Tom Cavanagh, and the actor wastes no time in reminding us why he was one of the best things about season 1.

For me at least, this episode finally crystalized a few plot points, and with luck next week's episode will begin to focus the narrative through them to a dramatic mid-season cliffhanger.

The arrival of another "breacher," a female Earth-Two thief nicknamed Dr. Light, gives Wells the idea to lure Zoom out by capturing his latest emissary.

Fears are a natural human emotion, but it is only by facing them that we find our way out of the dark. If any character on The Flash wants to be worthy of the title "hero", then they must face the darkness inside.

Jul 30, 2018 | Rating: 4.5/5 | Full Review…

The Flash is just a better show when Tom Cavanagh is on it. With the formal reintroduction of Harrison "Harry" Wells on The Flash Season 2 Episode 5 everything feels right with Earth 1.

Jul 27, 2018 | Rating: 4.5/5 | Full Review…

The Darkness and the Light is The Flash at the peak of its powers, delivering an episode that moved with purpose, has an interesting villain and contained healthy doses of both drama and comedy.

Jul 27, 2018 | Rating: 9.5/10 | Full Review…

After four episodes full of questionable choices, The Flash delivers the best second-season episode thus far.

Jul 26, 2018 | Rating: 3/5 | Full Review…

Darkness serves as our proper introduction to Harry, who, in his own universe, seized the metahuman outbreak as a business opportunity.

Jul 26, 2018 | Full Review…

It's clear that most of this episode's resolution won't happen until next week, but so far, so good.

Jul 25, 2018 | Rating: 3.5/5 | Full Review…

While the baddie of the week can be fun (and Doctor Light) certainly is, what keeps the show rooted is the dynamics between characters.

Jul 25, 2018 | Rating: 9/10 | Full Review…

A fascinating development, one that makes Season 2 a little weightier while still remaining the bright, light show that we love.

Jul 24, 2018 | Full Review…

The darkness is present, but it's not oppressive; it's the light that keeps The Flash at the top of the TV superhero game.
