I wonder if DC would be interested in doing something of a soft reboot of their franchise. Instead of focusing on their big names, maybe it would be good to go smaller for a bit.
The thing about the engine of superhero movies is that it’s usually driven by building up from success no matter where you find it. A lot of more obscure character hits set the momentum for what followed. Blade kickstarted the current wave of superhero films, but after that Iron Man has to be the best example. Then the somewhat unexpected size of the success of Ant-Man and Guardians sent Marvel in another direction.
With Warner Brothers, Wonder Woman has so far been their only unequivocal hit critically and financially. It exceeded expectations. Unfortunately, Justice League was already barreling ahead so there was no time really to take advantage of what Wonder Woman did.
However, I think the next new DC film (not a sequel) could be very good if they used what Wonder Woman gave them. For me, I think the New Gods or Scott Free Mr Miracle movie would be a good idea. Like Iron Man, he’s not a character people are generally familiar with and he would be a fresh face in the series. Also, Wonder Woman set up the idea that the “Old Gods” died in a war with Ares, so it’s already laid the groundwork for the New Gods to start popping up in our world to take their place.
A while back, WB Animation had plans for a New Gods feature with Scott Free and Orion in the lead roles and the script I read was quite good. Also, Mike Mignola did the character designs.
I think with some modifications it would be a good script to fit into the Wonder Woman universe and give Warner Brothers a chance to break out of this icon driven juggernaut approach to their movies.
