Even without the general DC live action dictate that these characters are serious stuff and not
This _should_ be Superman. But they can't have a Superman in the show's premise. It could be Batman, but Batman was decreed off limits. So they made it Oliver Queen - he's passionate, has resources, and can be made into a credible leader type. Except Ollie isn't the crystallization character - he's the irritant. The almost outsider who keeps forcing the rest of the League to defend what they're doing, to focus on the little guy, to point out worst case scenarios and otherwise start social conflicts. That's true whether he's the urban hunter or the loudmouthed idealist. That's the big tweak to the character. And the Oliver Queen in Smallville was popular. Popular enough to give him his own show.
But then they didn't build on the Smallville basis but re-set that type of Oliver in a new setting, which is now the core of the growing TV universe, inspiring the new Flash. And that decision just puts everything else a little off kilter. It should be Barry, or Hal, or best of all J'onn acting as the core of the team if the big trinity is off limits.
No real point to this, just some observations on how comics translate to TV. Ill do more later on how this can work for supers gaming based one existing properties.
