We still have not seen a Flash movie or a Wonder Woman movie. Pretty well every major Marvel character has gotten a movie and now Ant Man and Guardians of the Galaxy are getting movies before Flash and Wonder Woman. That is the problem I have, even when DC was on top, they did nothing with a lot of characters, just focusing on their two big franchises.
To be fair, there was a live-action FLASH television series launched immediately in the wake of the 1989 BATMAN movie. And BIRDS OF PREY and THE HUMAN TARGET and LOIS & CLARK and, of course, ten years (!) of SMALLVILLE. And now ARROW.
Granted, those were TV, not movies, but it's not as though DC was letting the rest of its list go fallow. They just seemed to be focusing more on the small screen than the big one.
(And how many live-action Marvel TV shows were there during that period?)
One little problem, I think generally super heroes don't work on the small screen and I think most of those shows were garbage.
Really Flash and Birds of Prey didn't last past one season, Smallville was pretty and it had the reverse problem, it went on way too long to the point that Clark faced and defeated most of his rogues gallery before becoming Superman.
The problem with live action super hero TV shows, it seems they have to make things less epic and more mundane just to make things work on a TV budget, that's why we got that lame smoke demon Darkseid on Smallville.
I think if they tried to X-Men on the small screen, it would end being like the Mutant X TV show, if they tried to do Justice League on the small screen, it would end up like the Justice League TV movie from 1997. Arrow is okay, but that is its more straight forward concept, no one really has any super powers, so its easier to make that stuff work on a TV budget.
I would rather see a Flash movie and Wonder Woman movie, then another attempt at a Flash TV show and Wonder Woman TV show, especially after that bad Wonder Woman pilot.
Frankly I even think the cartoon shows based on super heroes generally do a better job at capturing the spirit of the comics then the live action TV shows.
