As much as I'd love a Green Arrow movie, I'd honestly prefer a tv show. Ollie's stories work best when you already know him. I don't know about anybody else but it's the older Ollie that I really like. The one with the family and history. Young Green Arrow is literally a Batman knockoff. He's supposed to be.
I think it would be better to go the No Ordinary Family/Smallville route but darker at times. I mean look at his best stories. The Longbow Hunters, his road trip with Hal Jordan, all of his books since he returned from the grave (when Kevin Smith brought him back anyway). Playing on his history makes for the best stories imo.
Yeah there could always be another origin movie and people could make all the Batman and Iron Man comparisons even before the movie comes out but I'd much rather that kind of thing be something he glosses over or is kind of common knowledge. For me a good Green Arrow story isn't defined by Ollie's deeds or action sequences but by his interactions with the people around him. Otherwise he's just a Batman stand-in (like Smallville made perfectly clear even with the revamp). And this is coming from a Green Arrow fan. I'd much rather see stories involving Ollie and Dinah and maybe throw in Roy, Conner, and Mia. It's his wonderful cast of characters that make GA interesting and it doesn't get much better than Team Arrow. It's not like he has a butler or Lucius Fox or anything.
