I reread it recently and it's a story that is CRYING out to be filmed. I always thought a Flash movie should feature more than one incarnation of the character. Obviously not a verbatim adaptation - certain things would have to be changed obviously. Here's how the basic story would go.
- A pre-title sequence shows Barry Allen working in his lab. Lightning strikes and bathes him with chemicals resulting in him receiving his powers.
- Title Sequence
- Cuts to five years later. The Flash is an established hero in Central City. However he's obsessed with trying to become even faster.
- Wally West is sent to live with his Aunt Iris. The story will be sort of told through his eyes. He's an awkward teenager and a bit anti-social. He rejects Barry and Iris somewhat even though they only want the best for him.
- Barry Allen is trying to recreate the accident in his lab hoping it will double his speed. He sets up a conductor to try and attract lightning to the lab and is waiting for a stormy night in which to conduct the experiment. This is mainly because of a main villain who is terrorising Central City (not worked out who that would be just yet).
- Wally West visits Barry's lab and a freak storm occurs. Instead of hitting Barry, the lightning hits him - giving him the same powers.
- Barry reveals to Wally that he is the Flash. Wally becomes Kid Flash and together he and Barry fight crime. Barry is very much a mentor to Wally.
- Wally loves the fact that he now has the same powers and is Kid Flash. His attitude improves and it helps him settle down more.
- In a conflict with the main villain Barry is seriously injured and falls into a coma.
- Wally West takes on the mantle of The Flash to defeat the main villain.
- Barry awakens from his coma to the news of what Wally has done and tells him he's proud of him.
- Wally is now happy in Central City with Iris and Barry.
The relationship between Wally and Barry would be similar to the relationship between Neo and Morpheus in The Matrix movies.
Then Barry could be part of a future Justice League movie and Wally could be part of a future Teen Titans movie.
I don't know if the DCEU plans include on doing the story in this way - but still, nice idea isn't it?
