Wonder Woman has a pretty large fan base thats been wanting a film adaptation for quite sometime, not to mention a tv series has a huge potential to fail especially with the people rumored to be attached behind it. Its a bit of a unnecessary gamble, especially since this would be the first wonder woman live action adaptation since way back then. With superman there was a whole bunch of movies with Reeves that are actually still relevant to this day not to mention the numerous rumors of so called Superman flicks back in the late 90's early 2000's before we got SR. Superman has always got alot of attention where Wonder Woman has got little to nothing. I believe WW needs atleast a shot at the big screen so it has a chance to be taken seriously, and i assure a WW movie would surprise a lot of people because it has a lot of potential.
I also think WW has a larger audience then what all the skeptics think, i mean this is really an iconic comic book character in general and a lot of die hard comic book fans like myself have to respect that and would love to see how it gets adapted on the big screen. We've seen resident evil, underworld, tomb raider, kill bill, etc. with female leads and do pretty well and they dont have as big of a fan base as imo wonder woman does when it comes to a already established fan base, people that have been reading the comics for ages.
