Neo. The Only. The One.
THE ONE
I feel like they're putting Flash in a weird position for any other movies going forward.
Considering you started with "Big multiversal chaos with two Flashes, three Batmen and a Supergirl," how are they gonna do another Flash movie where he fights Captain Cold or some shyt? General audiences are gonna look at that and be like, "That's some CW shyt. "
I wonder the same about Miles since his first box office movie was Spider-Verse.
Fact of the matter is... Captain Cold was always a dumb villain for the Flash.
Most of his villains are dumb. The only thing he should be fighting are kryptonians (or folks stronger or faster than kryptonians), reality warpers and other speedsters. That's the only thing that would make a character like Flash believable.
Edit: Telepaths too as thought travels at the speed of light.
