Being a Flash aficionado and collector of Flash comics, I miss some of the really central things to the Flash mythos from the Silver Age forward. As a starting principle, the Flash has the best Rogues Gallery of any superhero, hands down. There was no need for "meta-humans" and the introduction, character development and first appearance of all villains, save for Captain Cold, is being handled clumsily.
I fear the same is in store for the introduction of the Reverse Flash. Geoff Johns is one of the screenwriters and we are getting his ret-con version of the Flash's origin, working in the death of his mother. Other than the pilot where Grodd's sign is hanging on a cage, there is no hint of his appearance. Grodd, Reverse Flash and other villains are staples of the Flash stories. The key here is to develop new fans, without losing the old fans and Geoff Johns is nearing leaving real fans behind. Flash's costume sucks. One cool thing in the comics was his costume coming out of his ring. Here there is no explanation where his costume is, etc.
Johns also fails to recognize that the Flash is NOT a detective, even as Barry Allen he is a police scientist. The intro of Captain Boomerang is like a detective story. The Flash is a balls out confronter of bad guys; action is the essence of this superhero, not ruminating about who this bad guy is and why he is acting this. The Flash is not Jungian, he is Schwarzeneggerian. HE IS ACTION!!
We will see with Grodd and the Reverse Flash whether they can focus on titanic stuggles and leave the psychoanalysis to the professionals.
