There has perhaps never been a shared universe on television quite like the Arrowverse.
Spawned by Greg Berlanti back in 2012, the juggernaut-to-be came to life with Arrow - a dark reimagining of the origins of DC Comic character Green Arrow as a once-shipwrecked Oliver Queen returned to Starling City to right his family's wrongs. In doing so, the character would inadvertently start a trend of costumed vigilantes - many of whom attempted to follow in his footsteps.
Following two successful seasons of Arrow, The CW commissioned The Flash - a show that, in one season, outperformed its parent show in just about every way possible, going on to become a huge hit for the network. And soon, others would follow with DC's Legends of Tomorrow giving some of Arrow and Flash's lesser-appreciated supporting characters some much-needed spotlight, and Supergirl showing audiences just how powerful 'girl power' really was.
Now, here we are seven years later, and there have been 20 collective Arrowverse seasons (seven of Arrow, five of The Flash and four of both Supergirl and Legends). And with Arrow set to conclude following its eighth outing, and Batwoman joining the fray, what better time to look back at every season so far just to see which of them truly saved the day (and which of them "failed this city")?
