ITVX is currently streaming all six seasons of a popular superhero drama that took the comic book fandom by storm over the past 10 years.
Following the adventures of one of the most beloved heroes from the pages of DC Comics, it’s a must-watch for any fans of the latest big screen Superman movie which is still wowing audiences.
It originally aired on the CW from 2015-2021 and developed a passionate worldwide following.
Every single episode of Supergirl is now available to watch completely free of charge after recently being added to ITVX.
Starring Melissa Benoist as Kara Zor-El, aka Kara Danvers, the young hero and cousin of Superman vows to become her city’s protector while juggling personal revelations and a series of threats to Earth’s safety.

A spin-off from the CW’s Arrowverse series based on DC heroes, Supergirl is considered by many to be the best of the bunch as it adapted several fan-favourite stories and characters from the Superman mythos while breathing new life into the iconic tales.
Rotten Tomatoes critic Sean Axmaker wrote of the show: “It's a well-made series with a likable hero, a solid supporting cast, and a sense of optimism that is refreshing next to such dark shows as Gotham.”
Steve Wright of SciFiNow agreed with the assessment: “All in all, it's a solid first outing for Supergirl, and with the series' future now in the hands of The CW, the future looks suitably optimistic.”
Eclipse Magazine went a step further, writing: “I need a show in my life that's about hope.
“Supergirl provides just enough sugar in an otherwise bleak diet. People used to dark and grim, need not bother, it's not for you. The rest of us will enjoy it for the pure, blissful fun that it is.”
There are also plenty of five-star Google reviews from fans, including from this one who raved: “Constantly amazed by the wide-eyed and hopeful Kara Zor-El who continues to grow as Kara Danvers, rather than letting her Supergirl persona take over.
“Benoist and her supporting cast constantly put on spectacular performances that are sure to touch your hearts.
“Superman aside, make way for Supergirl, the hero that everybody needs and deserves.”
And a final fan claimed: “This has become my favourite show ever, I have watched it 6 times and it still hasn't got old for me.”
With House of the Dragon’s Milly Alcock stepping into Supergirl’s red boots for the foreseeable future, comic book fans now have the perfect opportunity to brush up on the hero’s earlier adventures.
Supergirl is available to stream on ITVX.
