Supergirl is currently streaming in Australia on HBO Max, and in the US on Netflix, and it earns its premise rather than just borrowing genre trappings. 6 seasons in, and the quality has not slipped. A 7/10 rating says what the writing already makes obvious: this one works. Melissa Benoist sets the tone, and the world-building does the rest. Put it on tonight on HBO Max and see for yourself.

There is a reason Supergirl keeps coming up in conversation. What makes Supergirl work is that the ideas never crowd out the people having them. Twenty-four-year-old Kara Zor-El, who was taken in by the Danvers family when she was 13 after being sent away from Krypton, must learn to embrace her powers after previously hiding them. The Danvers teach her to be careful with her powers, until she has to reveal them during an unexpected disaster, setting her on her journey of heroism. Melissa Benoist and Chyler Leigh lead a cast that makes the ambitious moments land. Across 6 seasons (2015–2021), it never lost the thread that made it worth starting. The rules of Supergirl's world are consistent enough that the big swings never feel like cheating. It delivers reliably on what it promises, which is more than most of its competition manages.

Supergirl is satisfying on multiple levels — something to watch and something to think about after. Superman & Lois is the obvious comparison, but Supergirl earns its own place alongside it. 6 seasons is a lot, but the quality holds all the way through. Melissa Benoist's performance is the anchor the more ambitious moments need. The world-building pays off in ways you will not anticipate on a first watch.

Supergirl wrapped up in 2021, created by Greg Berlanti, Andrew Kreisberg and Ali Adler — and 6 seasons are available to watch from start to finish.
