It's not a "challenge" if all it amounts to is "I don't like your opinion, and it smells!".
Superman is dull and boring and would hold little interest with people, if he were to be the clean cut, simple, flat character he was in comics. The whole "hope" symbol stuff is hilarious and merely furthers the infantilisation of the audience that DC trades in.
This is why their biggest success is always Batman. And now, after copying the whole plot, style and tone of Captain America: TFA, Wonder Woman is another of their "non-DC" successes.
I have nothing against DC, I enjoyed the infamous Ryan Reynolds GL film, and really liked the Nolan and Burton Batmen.
I just don't see their prime properties working. Maybe Green Arrow could be done for the big screen or a Catwoman movie or something, but the big S is destined to be a big L, imo.
