He's got the second greatest DC rogues gallery

Heck, his main villain team is called 'The Rogues'. 
Why can't we have a Flash animated series, beginning with Barry and adapting various Silver Age stories? 
The main villains would be Captain Cold, Gorilla Grodd, Professor Zoom and the Rogues Gallery - naturally. The Rogues Gallery appearing infrequently as a team, with the more high-profile individual members appearing solo frequently enough to develop their character. 
Barry also has a good supporting cast. 
I'm just thinking, animated series for Barry is the way to go.
