Yeah, this Green Arrow has to be the JLU version, otherwise it will probably flop.
My guess is you guys never read the comics, otherwise you'd know the JLU version is basically the comics version. Post-revamp, that is.
Yes, originally Ollie Queen was a poor Batman knock-off, but the revamp by Denny O'Neil & Neal Adams, turning him into a left-wing bleeding heart playing the conscience of the larger than life heroes of the DCU made him one of the most interesting characters in superhero fiction.
But, alas, I'm afraid The CW will water down the whole left-wing aspect. They did that with the SV version. But even so, Ollie still managed to be the most interesting character of seasons 8-10.
