Green Arrow has been around for a long time, and at this point his time as a Batman pastiche and a more original character is about even. At this point, have his stories and characterization done enough to make him an A-List hero, with the likes of your typical Justice Leaguers?
Has Arrow, in particular, done enough for the character to make him a recognizable hit outside of comic book circles?
Do you think he's on the cusp, but missing something to make that happen?
Do you think he's firmly (and potentially eternally,) B-List?
Or do you think he's still a poor-man's Batman?
Personally, I think he's wholly established himself as a unique individual street-level character. His characterization has shifted to the point that, I think his stories are a lot different than people with little knowledge of current Arrow would expect.
Personally, I think he's on the cusp. I think we'll really see how he's addressed as a character in the next few years, depending on what WB and DC can do with the character outside of comics, whether that be more Arrow or a potential Green Arrow movie.
