I'm a sucker for a training montage. I wonder if they're going to flashback to the island where he learned to use a bow. Just hopefully not with Lost/Once Upon A Time's frequency.
I'm not sure why they didn't just make it a spin-off of Smallville. Not that I want more of Smallville, mind you. Justin Hartley was pretty good, though, and I generally didn't mind his scenes as Queen (outside of just wondering why there's more Green Arrow than Superman, but that wouldn't be a concern in a show about Green Arrow).
