Taking major inspiration from the acclaimed Green Arrow: Year One by Andy Diggle and Jock, we first meet Oliver Queen after years of his being stranded on an island. Upon his return to civilization and reuniting with his friends and family, he tries to keep up the appearance he held before. But secretly he begins to dawn a green hood and arms himself with a bow and arrow to take his vengeance out on those who have "failed this city". Thanks to flashbacks to the island when see the story of how a spoiled rich kid became a hardened vigilante. Early in his adventures, Oliver is joined by his bodyguard Diggle who influences the angry young hero for the better ultimately turning him into the superhero he would become. Of course in our tech-based era they would need help on the technology front of the mission and turned to the quirky IT expert Felicity Smoak.
Arrow found success with comic fans and mainstream audiences alike. Seeing fan favorite DC Comics characters and elements grounded in a realistic setting proved to be a thrill for many. The Royal Flush Gang became a group of thieves who adorned their helmets with playing card designs. Count Vertigo became "the Count" a prominent drug dealer in Starling City. Green Arrow's least theatrical enemy from the comics, Eddie Fryers proved to be a natural fit for the show as the villain in the flashback story thread.
Naturally a second season was green-lit and many see this as the show's best. Not only did it introduce more characters from the DC Universe like the Flash (who would spin-off in his own show), but the overall stakes for the season were much higher. Oliver's old ally from the island, Slade Wilson AKA Deathstroke rolled into Starling City with his own allies to bring trouble to the Green Arrow. But for a man who started out as a
As with just about any show which has come about in the age of social media, there has been plenty which turned fans off. When Felicity was introduced to the show as a recurring character, it became noticed that actress Emily Bett Rickards and Stephen Amell had a natural chemistry. This meant the historic coupling of Green Arrow and Black Canary which was seemingly planned was sacrificed to the altar of what was dubbed the "Olicity" pairing to the chagrin of many comic fans. Felicity herself evolved from a fun, quirky and believable tech expert into a full on deus ex machine plot element. She went from hacking into villain's computers to hacking into nuclear warheads. Those behind the show seemed to struggle with the tone of the show from season to season. While started as a show based in reality they began to pump more traditional superhero-y elements into it before trending back to the grounded feel. Oliver Queen went from inheritor of his family's company to losing everything to being mayor
As the series came to an end it seemed fitting it do so as the heroes across the Arrowverse faced their greatest challenge in the ambitious adaptation of Crisis on Infinite Earths. In the opening episode of the crossover; Green Arrow joined his allies: the Flash, Supergirl, Batwoman, White Canary, and Superman in defending the multiverse from the Anti-Monitor and gave his life trying to save as many people as he could. In death, Oliver Queen would become the host for the supernatural being the Spectre and would use his newfound status to not only help defeat the threat they faced but also bring rebirth to the world. Meaning now the Arrowverse all takes place in a world which exists thanks to him. Once the Crisis wrapped the final episode of Arrow was devoted to those he left behind as they mourned his death but also honored the legacy of one of TV's greatest superheroes.
