Supergirl: All 6 seasons ranked from worst to best

3. Season 2

Supergirl‘s second season marked the beginning of a new era for the show. With production in Vancouver underway and Cat Grant set to depart, there were big changes in store, and one of them came early on in the long-awaited arrival of Superman.

Tyler Hoechlin’s charming and warm portrayal of the Man of Steel proved a better on-screen partner for Kara than the messenger she used to contact him in the first season, and seeing the pair team up throughout the season was one of its most fun elements.

But season 2 is also where the writers began to tackle more serious storylines, with the underground alien fight club and slaver’s moon providing the season with some of its richest material. And we can’t talk about the second season without discussing Alex Danvers’ emotional coming out story, which resonated with viewers across the world and paved the way for more representation in the superhero genre – an impact that will continue to be felt longer after Supergirl‘s conclusion.

This season also saw the introduction of important characters like Lena Luthor and Mon-El – both of whom would go on to have a major impact on Kara’s life. And, in spite of a few hits and misses along the way, their respective stories brought the season towards that incredible two-part finale that saw the Daxamites invade and Supergirl take her rightful place as the champion of planet Earth.
