Supergirl: Season 3 (2017 - 2018)




Critic Consensus: Heavier themes lead to higher stakes, but Supergirl gives its eponymous heroine and her fellow supers plenty of room for growth, creating a well-balanced, engaging third season.

It was just full of depressed heroes, drama and angst, and had so little actual superheroics and fun...

The most intriguing, engaging, and spectacular season of the series to date.

[Supergirl] uses the laziest possible storytelling tactic, and [it] annoys the hell out of me.

J'onn J'onzz on Supergirl has always been delightful, but it has gotten even better this past season when they brought [in] Carl Lumby...

Superb writing.

Supergirl is a show that's smarter than it's sometimes given credit for.

Apr 18, 2018 | Full Review…

If Supergirl spends its [third] season letting Kara Danvers rediscover herself, one moment of solace at a time, it'll be a season well-spent. If not... well, it'll probably be pretty good, no matter what it does.

Supergirl continues to make the case it's a much improved show with Mon-El up, up and far away.
