Why can't DC make decent NON-Batman/Superman flicks

Yes, Green Lantern sucked... but that's old news. Superman is getting a Reboot. Batman is getting a Third movie... Still we have NO Wonder Woman, NO Flash, but they want to do a Justice League movie cause Avengers did well...

Aquaman is a movie that has to be treated carefully in order to work... somehow I expect a ton of jokes on Aquaman to show up... How can he fight crime out of water or asking Goldfish to stop bank robbers kind of jokes...

And that's the biggest problem with DC's heroes... They are too "Perfect" and lack "real flaws" that make them relatable... At least Batman has the whole Parents are dead thing going for him...

Wonder Woman, Aquaman, Martian Manhunter, Hawkman, etc. would be a bit hard to translate into film... but if Marvel could pull out THOR, Wonder Woman shouldn't be THAT hard...

Out of the bigger DC heroes, Flash seems to be the easiest to do... Why haven't we gotten a Flash movie is beyond ridiculous... If we were able to get a Flash TV series in the 90s, then I don't get how a Flash movie hasn't been made yet...

DC/WB missed a huge opportunity to make a Flash movie back when shows like CSI were a hit...
(cause Barry Allen/Flash is a CSI himself)

To make a JLA movie they should have gotten a few DC heroes out aside the big Blue and Bats...
I think they made a TV JLA movie...

At this rate looks like DC should stick to animated movies...
