Critic Reviews for A Flash of the Lightning

I'm genuinely excited to see how all of this shakes out.

By toning down the superheroics early on in order to have a sufficient budget to pull off the Crisis. That makes for an episode more concerned with character development than flashy special effects, and for the most part it works pretty well.

"A Flash of the Lightning" is a relatively quiet and introspective episode after the bombast (and perfect Queen needledrop) of "Into the Void."

The Flash is finally finding nuance by treating the metas as actual people instead of an evil they must defeat. That's made all the difference.

Based on these first two episodes, Season 6 may well restore some of The Flash's missing shine. The series is definitely attempting to cover too much ground so early into the season, but at least it's able to build momentum along a number of fronts.

It's safe to say that things will never quite be the same.

There are some other nice moments here: the highlight being Jesse L. Martin doing what he does best: giving inspiring speeches with nearly a tear in his eye.

Man, the second of these pre-"Crisis on Infinite Earths" crossover episodes was an emotional doozy, for those in Central City and us at home.

It is such an exciting development because it can bring a new dynamic to The Flash.
