The effects and fight sequences continue to impress, expanding the boundaries of what can be accomplished for television.

All in all, a promising debut in the new home.

A mixed bag, but most of the returning and new characters are good and/or get some good development. The overall storylines are fun to follow and the finale delivers, mostly.

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

Supergirl improved in many ways in Season 2, but the show hit plenty of bumps in the road this year.

Oct 11, 2016 | Rating: 7.3/10 | Full Review…

Between Benoist and Flockhart's performances and Kreisberg and Jessica Queller's script, its believability leaves much to be desired, but its focus never falters

Jul 17, 2018 | Full Review…

Season 2 built strongly upon the firm foundations of season 1 and delivered a fantastic second season that has set a new standard of excellence for DC shows.

Jul 11, 2018 | Full Review…

While the season finale is a high point of the series, it also exemplifies a lot of the problems that arose during Season 2.

Jun 21, 2018 | Full Review…

We don't find out much of any info about dude this episode but you can bet your bottom Brainiac that this is one of the first times that Supergirl blatantly yet smoothly set up a storyline for deeper into the season.

Jun 12, 2018 | Full Review…

The move away from so much time spent with Linda Danvers, the secret identity of Supergirl, chatting with Cat Grant (Calista Flockhart) helped move this series from being a soap opera with a female hero to a much better action series.

Aug 24, 2017 | Rating: 3/4 | Full Review…

In the end, Supergirl/Kara followed her heart and it paid off for everyone.

Jan 24, 2017 | Full Review…

Alright, so this is a show about Supergirl, but let's make this thing clear from the start: Tyler Hoechlin is the best live-action Man of Steel since the sorely underrated Dean Cain hung up his tights.

Oct 25, 2016 | Full Review…

It's a very strong start to the new season, with lots of new threads to take hold of. Up, up and away!

Audience Reviews for Supergirl: Season 2

  • Sep 29, 2020
    Not as strong as the first season but still excellent.
  • Aug 03, 2020
    Flockhart is missed but the additions are great and the story is just as good as ever.
  • Apr 05, 2020
    Decent followup to the first season, but they overdue it with some plot lines.
  • Apr 04, 2020
    Not bad, but I think the TV series is starting to fall apart, literally. The problem here is that it relies too much on Superman, his villains, his allies, etc. As a comics fan, I keep on noticing how similar Supergirl is to Superman (it's not even an exaggeration to say that she 'is' Superman himself). I would like to see her own unique story, if you know what I mean.
  • Mar 03, 2020
    Boring and uninspired. Oh and awful special effects.
  • Jan 11, 2020
    mon el was horrific and i miss lucy lane. but maggie and lena were fantastic.
  • Dec 28, 2019
    Fun, exciting and action-packed, Supergirl's second season is even better than the previous season because of it excellent direction, current script, cutting-edge visual effects and charismatic and captivating performances by Melissa Benoist, Mehcad Brooks, Chyler Leigh, Jeremy Jordan, Floriana Lima, Chris Wood and David Harewood

    mint can't stop watching
  • Dec 11, 2019
    The level of pure stupid, lazy writing was off the chart. When I watch tv shows like this I always give a certain amount of leeway when it come so silly scientific stuff or technical blunders, otherwise I can't enjoy it. But there was no way to ignore the stupid in this season, the massive level of just not giving a c**p by the writers. I literally sprained my eyeballs from rolling them too much.

    Again, not all superhero content is great. But its on network TV so expectations are always very low. We need better female superhero content please
