[Full Review in Spanish] Aug 7, 2019 | Full Review… John Tones Espinof It was just full of depressed heroes, drama and angst, and had so little actual superheroics and fun... Feb 17, 2019 | Rating: 2/5 | Full Review… David Hogan hoganreviews.co.uk The most intriguing, engaging, and spectacular season of the series to date. Sep 25, 2018 | Rating: 8/10 | Full Review… Andrew Pollard Starburst [Supergirl] uses the laziest possible storytelling tactic, and [it] annoys the hell out of me. Jul 5, 2018 | Full Review… Alyse Wax Syfy Wire There was a lot to process, in what felt like a chaotic end-cap to a very uneven season. Jul 24, 2018 | Full Review… Allison Keene Collider Light and breezy and fun, fun, fun. Jun 26, 2018 | Full Review… Matt Webb Mitovich TV Line 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... Jun 20, 2018 | Full Review… Princess Weekes The Mary Sue Superb writing. Jun 18, 2018 | Full Review… Ja-Quan Greene Black Nerd Problems Supergirl is a show that's smarter than it's sometimes given credit for. Apr 18, 2018 | Full Review… Caroline Siede Consequence of Sound 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. Dec 12, 2017 | Full Review… Allison Shoemaker CBR Supergirl continues to make the case it's a much improved show with Mon-El up, up and far away. Nov 2, 2017 | Full Review… Jeffrey Lyles Lyles' Movie Files After an entire summer away from these characters, it's tough to come back and see our heroine so far removed from everyone else. Oct 16, 2017 | Full Review… Jordan Alsaqa TV Equals View All Critic Reviews (15) Audience Reviews for Supergirl: Season 3 Sep 29, 2020 Enjoyed this season, great stories, easy to watch. Just put your brain on a neutral and enjoy it! Philip B Aug 09, 2020 This was awesome but it wasn't the best Daniel20 S Aug 03, 2020 More political and just as much fun, Supergirl is a great show not afraid to tackle big issues. Steve D Apr 07, 2020 not that bad, even in spite of the fact I hated her defeating super man it was entertaining time godofredo c Mar 03, 2020 Boring and uninspired. Oh and awful special effects. Oronzo C Jan 14, 2020 With even better character development, great action scenes, good visual effects, a excellent script, creative direction and exceptional performances by Melissa Benoist, Mehcad Brooks, Chyler Leigh, Jeremy Jordan, Katie McGrath, Odette Annable, Chris Wood and David Harewood, Supergirl's third season achieves the hard feat of beating its predecessors ANDREY A Dec 04, 2019 Not as good as Seasons 1 & 2, but Supergirl Season 3 still has a lot of gems on her sleeves and cape. I still have no idea what's not to love about this show so far. The pacing has gotten better, the characters are great, and the acting still holds up for being a cheesy CW show. But then again, I haven't seen Seasons 4 and 5 yet. Michael O Nov 27, 2019 It was.... ok.... this marks the start of its failing. Kristopher H Nov 08, 2019 Not as strong as the first 2 series but enjoyable Roy R Nov 03, 2019 This Season of Supergirl has it's ups and downs but through and through it's a good season.
