James Gunn's "Superman" promotes kindness as the new punk rock. It's a hopeful message, encouraging people to treat each other better rather than fall into the cynical trappings of modern society. It isn't a new concept by any means, since another TV show about the Man of Steel's famous cousin laid the foundation for this bright, buoyant world where superheroes wear their emotions on their sleeves (and capes).
Premiering on Oct. 26, 2015, the "Supergirl" TV series marked the third entry into the burgeoning Arrowverse – an interconnected television universe featuring different DC series. Funnily enough, it was meant to be separate at first, but once the show moved from CBS to The CW in its second season, it integrated into the wider storyline. It was a strange time for the DC brand, though, mostly due to its cinematic endeavours attempting to build a darker alternative to the Marvel Cinematic Universe (MCU), while the Arrowverse proved to be a smorgasbord of tone. "Arrow" brooded and "The Flash" brought levity, but "Supergirl" became the heart of it all.
