The tone of this season of Arrow must have reminded you of the first season when the world was much simpler, the story is grounded, flashback scenes are gritty and villains are more relatable. It seemed that the new season deliberately distanced itself from the supernatural elements and embracing its own roots.
The big villain of season 5 has been Prometheus (D.A. Chase) and he doesn’t have supernatural or magical powers, which in a sense a major “callback” to the first season where Malcolm Merlyn was the big villain attempting to wipe out the entire area called “Glades” off the map of Starling city through a sinister “Undertaking” which took the life of Oliver’s friend & Malcolm’s son Tommy Merlyn.
The format of Arrow has been a back and forth between Oliver’s haunting past and tense present, he has been living a double life since he came back after five years in hell. Each season showed one year of his life on the island, which means the fifth or current season will actually show the audience how he actually escaped. This will bring the show to full circle to the very first episode when he was rescued.
The executive producer of the show Wendy Mericle hinted at the death of major characters, he said:
“Chase has been trying to prove to the world and to Oliver that he’s not a hero, he’s a killer, and he’s going to pull out one final, big whamo at the end that’s going to leave Oliver reeling. We might lose some people.”
The fact that Team Arrow is going to all-out war against Prometheus suggests he is the most dangerous and terrifying villain of all seasons. In fact, Oliver Queen is seeking assistance from Slade Wilson a.k.a Deathstroke, Black Siren, and Nysa Al Ghul to take down one man. Well, technically he also has the support of Talia Al Ghul. Oh my god…we will see both sisters on a single frame. This will be EPIC!
