All Critics (7) | Top Critics (1)

For now it's worth celebrating just how strong Supergirl's fourth season has been.

It also sowed the seeds for the incoming "Crisis On Infinite Earths" crossover that's sure to shake up the Arrowverse like never before when it arrives this fall.

May 20, 2019 | Full Review…

The season 4 finale of Supergirl, "The Quest For Peace," masterfully resolved all of its outstanding storylines.

May 20, 2019 | Full Review…

A sincerely good conclusion to a season that ended up being one of the most entertaining seasons of supershows the CW has done.

May 20, 2019 | Full Review…

There are so many threads that they tried to conclude at once, which meant that none of them wrapped up with any sort of satisfaction.

May 20, 2019 | Full Review…

As Supergirl's fourth season prepares for the reintroduction of Lex Luthor to a new generation, the series is as strong as it's ever been.

Nov 7, 2018 | Full Review…

Ultimately, Supergirl seems to have a sense of where it's going this season, but the question is whether we'll be excited to go with it.

    Stop making politics and show us stories. Good plot idea, but to much polirized to the leftism. If did not stop, its doomed!

    Great show. Love the addition of Lena Luthor as a complex character

    This season was kind of boring first 10 episodes but then it was really amazing. Whole Lex storyline was good, Acting was amazing and it left lot of space for next season. For me it was fir sure best arrowverse season for that year (flash s5, arrow s7, legends s4). So if you gave up on Supergirl try to give it a shot.

    Way too political. Kara is enjoyable in the crossovers, but in her show her only purpose is to be powerful and be complimented by the other characters to emphasize how powerful she is. Most characters are reduced to their gender, sexuality, or race. Nia, despite being transgender, actually felt fleshed out and more like a real character. The plot was fairly standard and predictable and clearly slanted to left wing politics. I used to like Supergirl, but it has become difficult to watch.

    The show was fantastic during season 1 and 2, then it completely fell apart after it meshed with the CW and the political machine of the liberal left. People watch shows to escape themselves into a new universe AWAY from your day to day political world. CW manages to shove it down your face. Goodbye CW and your shows!

    If Supergirl was done right, it would have been a must-see television show. However, with its subpar to at best mediocre acting by the cast, and an obvious politically correct charged writing since season 1, Supergirl is a must-skip.

    This is the worst incarnation of Lex luthor. He is over the top-cheesy and evil. He's evil just for the sake of evil and it seems like the way he's written is what an idiot's idea of a smart person is. He literally walks by a bunch of jail cells with prisoners playing chess, yells out moves as he walks by and gets checkmate for all of them. This is fucking terrible writing. Not to mention how over the top the political messaging is throughout the whole show. Look, I get it. Trump is bad. The Republican party is bad. Their stance on immigration is bad. I want to see a superhero show. Scoring cheap political points is ok for a politician. It's not ok when you are substituting politics for a good plot.Smallville's Lex luthor was written WAY , WAY better and had a long character arc instead of just being thrown into the show. Don't get me started on the whole "RUSSIA BAD" Evil supergirl shows up in russia of all places. What the hell is this? The 1960s? The fucking cold war? The show had a steadily paced and not too bad writing all the way up to season 3 but then it seems like for season 4 everything that was bad about the show was taken from a 5 to an 11. Look. I honestly like the idea. The writers clearly are more on the liberal side, but please, it's a fucking TV show. Entertainment. If your politics is becoming the point rather than entertaining people, you've failed as a writer. There's a reason why other shows are a lot more subtle in including politics. Here, it looks like a high school kid took his first writing class and said "CITIZEN LIBERTY = TRUMP METAPHOR", "EVIL SUPERGIRL IS RUSSIAN BECAUSE RUSSIA BAD" "LEX LUTHOR PLAY CHESS. LEX SMART AND EVIL." "CONSERVATIVE BAD" "WE GOOD." Then smacking you over and over with a CNN pamphlet repeating all these things. My point is, the politics shouldn't be the center focus of the show. It feels like the poltics and the metaphors and the symbolism came first, and the story came second. It should be the other way around. The show has become unbearable and it's not because I'm a Russia supporting Conservative who hates gays and loves trump. I'm a Bernie supporter. This season sucks and anyone who tells you otherwise is just saying it's good because they're afraid of the backlash they'll get for disagreeing with OVERT POLITICAL PROPAGANDA IN A SHOW BASED ON COMIC BOOK CHARACTERS WHO WEAR THEIR UNDERWEAR OUTSIDE. Rant over.

    Loved this show at first, but it's too political this seadon, I am bombarded with politcs constantly and would like a break, Im a centrist and Supergirl seems t have alienated anyone who isn't really left wing (have stopped watching some shows that are really right wing for the same reason). A super hero show should be for everyone, there are good people on thright and left, if a show is too far to o e side it will lose that audience and likely not survive, Supergirl WAS a great show, bit unless something changes, it's done.

    The best season in my opinion
