I guess it's the Green Arrow story. I'm not super familiar with this superhero, but after watching the first episode, I'm curious how close they follow the actual storyline.
This show's Green Arrow was stranded on a deserted island for 5 years, where he somehow learned archery and super hand to hand fighting skills. Not sure how he learned the hand to hand combat if he had no one to fight with.
Anyway, I think this show's filmed in Vancouver. The show seems pretty cool so far.
