Critic Reviews for Fallout

The divide between humans and aliens hit a little too close too home this season as the allegories continued in abundance.

But Supergirl season four is unabashedly political, in a way that would do its sister show Black Lightning proud. Supergirl had feelings and needed us to know them.

Powerful conversations, important messages and good old fashioned logic laced into its storylines, Supergirl once again proved that it's a force to be reckoned with... aside from a minor issue here and there.

Supergirl was always an important show, but with the writers doing what they can to tackle current events in what is as close as you can get to "real time" on a television series, the show's almost become required viewing for those lacking in hope.

Some enjoyable moments, but it is weighed down by the writing.

One of the best scenes of the episode is the scene of Alex comforting Brainy after his run-in with a bigotted restaurant owner he thought was his friend. Alex and Brainy's relationship is quickly becoming one of my favorites.

Mercy and Otis Graves continued to carry out Agent Liberty's anti-alien agenda, by successfully taking down two of the show's most formidable female figures.

Supergirl is always at its best when it balances fights, feels, and fun, and "Fallout" is packed with all three.

Oct 22, 2018 | Rating: A- | Full Review…

"Fallout" is a really smart episode, both in terms of what it wants to say and how it wants to say it. Plus it's an episode that utilizes the show's world and premise better than Supergirl has done since season one.

This was the perfect time to crack into Brainy's steely, logic-based exterior. While have a walking, talking deus ex machina is convenient, it's hard to feel too much warmth for him, in spite of Jess Rath's best efforts.
